The information we have below is just to give you an idea of what each area of primary SEN identified might mean. We have included the more obvious diagnoses, but remember, your child is unique and may well have difficulties that overlap in lots of different areas and may have needs that are not listed here that come under the categories we mention. It is important that you talk to your care-providers and professionals to understand your child or young person and the difficulties they face. Also remember that your child does not need a diagnosis to apply for an EHCP Education, Health, and Care Needs Assessment (EHCNA). 

Autistic Spectrum Condition 

Autism Spectrum Condition (ASC) is a complex neurodevelopmental disorder that affects how a person communicates and interacts with1 the world. At the bottom we have a section on how girls and women can present differently to boys. Symptoms can vary significantly from person to person, but they generally fall into two main categories:

1. Social Communication and Interaction: 

• Difficulties with Social Interaction:  
  • Avoiding or inconsistent eye contact. 
  • Difficulty understanding and responding to social cues (e.g., facial expressions, body language). 
  • Challenges initiating or maintaining conversations. 
  • Difficulty forming and maintaining friendships. 
  • Appearing to lack empathy or understanding of others' feelings. 
  • Difficulty with reciprocal social interactions. 
• Difficulties with Communication:  
  • Delayed speech development or absence of speech. 
  • Repetitive use of language (e.g., echolalia). 
  • Difficulties understanding figurative language, sarcasm, or humor. 
  • Unusual tone of voice or rhythm of speech. 
  • Difficulties with nonverbal communication (e.g., gestures, facial expressions). 

2. Restricted or Repetitive Behaviours or Interests: 

• Repetitive Motor Movements, Use of Objects, or Speech:  
  • Repetitive hand movements (e.g., hand flapping, spinning). 
  • Lining up toys or objects. 
  • Repeating words or phrases. 
• Insistence on Sameness, Inflexible Adherence to Routines, or Ritualized Patterns:  
  • Distress at minor changes in routines. 
  • Difficulty with transitions. 
  • Rigid thinking patterns. 
  • Need for sameness.
• Highly Restricted, Fixated Interests:  
  • Intense preoccupation with specific topics or objects.22 
  • Unusual or intense interests. 
• Hyper- or Hypo-reactivity to Sensory Input:  
  • Sensitivity to sounds, lights, textures, or smells. 
  • Seeking out sensory stimulation. 
  • Indifference to pain or temperature. 

Important Considerations: 

• ASC is a spectrum condition, meaning that symptoms can range from mild to severe. 
• Symptoms may change over time. 
• It is possible for individuals with ASD to have other co-occurring conditions, such as ADHD, anxiety, or sensory processing disorder. 
• It is also important to note that some of these traits can also be present in people that do not have ASD. 

If you are concerned about yourself or someone you know, it is important to seek a professional evaluation. 

ASC and Girls and Young Women 

It's increasingly recognized that Autism Spectrum Condition (ASC) can present differently in girls and young women compared to boys and young men.1 This has led to historical underdiagnosis in females.2 Here are some key ways these differences can manifest: 

1. "Masking" or Camouflaging: 

• Girls are often more likely to engage in "masking," which involves consciously or unconsciously suppressing autistic traits to fit in socially.3 This can include:  
• Mimicking social behaviours observed in others. 
• Forcing eye contact. 
• Scripting conversations. 
• Hiding repetitive behaviours. 
• This masking can be emotionally draining and lead to increased anxiety, depression, and burnout. 

2. Social Interaction: 

• Girls may have a stronger desire for social connection than boys with ASD, but still struggle with the nuances of social interaction. 
• Their "special interests" may be more aligned with typical female interests, making them less noticeable. For example, an intense interest in animals, books, or celebrities. 
• They might have a few close friendships, but struggle with larger social groups. 
• They may be more prone to internalizing social difficulties, leading to anxiety and withdrawal, rather than externalising behaviours. 

3. Repetitive Behaviours and Interests: 

• Repetitive behaviours in girls may be less obvious. They might involve:  
• Intense focus on specific fictional characters or narratives. 
• Excessive organization or list-making. 
• Repetitive mental activities, such as replaying conversations. 
• Their "special interests" might be less unusual or more socially acceptable, making them less likely to be flagged as atypical. 

4. Emotional Presentation: 

• Girls with ASD are more likely to experience co-occurring mental health conditions, such as:  
• Anxiety disorders. 
• Depression. 
• Eating disorders. 
• Their emotional distress may be internalized, leading to self-harm or other forms of self-destructive behaviour. 

5. Diagnostic Challenges: 

• Traditional diagnostic criteria for ASD have been largely based on male presentations, leading to underdiagnosis in females. 
• Clinicians may overlook ASC in girls who present with less obvious symptoms or who are skilled at masking. 

Key Takeaways: 

• The presentation of ASC in girls can be more subtle and internalised. 
• "Masking" plays a significant role in how ASC manifests in females. 
• Increased awareness and understanding of these differences are crucial for accurate diagnosis and appropriate support. 
• It is very important to remember that every person that is autistic is an individual, and that these are general trends. 

By understanding these differences, we can better support girls and young women with ASC and ensure they receive the necessary resources to thrive. 

Speech, Language and Communications needs 

It's important to differentiate between the difficulties experienced and the diagnoses given within SLCN. Here's a breakdown: 

Difficulties (Observed Challenges): 

• Speech Difficulties:  
  • Articulation errors (e.g., substituting sounds). 
  • Phonological errors (e.g., sound omissions or distortions). 
  • Stuttering/stammering (fluency difficulties). 
  • Voice quality issues (e.g., hoarseness, nasality). 
  • Difficulties with motor planning for speech (apraxia). 
• Language Difficulties:  
  • Receptive language problems (difficulty understanding). 
  • Expressive language problems (difficulty using language). 
  • Limited vocabulary. 
  • Grammatical errors. 
  • Word-finding difficulties. 
  • Difficulties with understanding and using figurative language. 
  • Difficulties with narrative skills. 
• Communication Difficulties:  
  • Pragmatic (social) language problems. 
  • Difficulties understanding nonverbal cues. 
  • Challenges with conversational skills. 
  • Auditory processing difficulties. 

Diagnoses (Formal Classifications): 

• Developmental Language Disorder (DLD):  
  • A significant language disorder that affects children's ability to understand and/or use spoken language, without any clear cause. 
• Speech Sound Disorders:  
  • Articulation disorder. 
  • Phonological disorder. 
  • Childhood Apraxia of Speech (CAS). 
• Fluency Disorder (Stammering/Stuttering): 
• Social (Pragmatic) Communication Disorder (SCD):  
  • Difficulties with the social use of language. 
• Voice Disorders: 
• Selective Mutism:  
  • Consistent failure to speak in specific social situations in which there is an expectation for speaking (e.g., at school),1 despite speaking in other situations. 
• It is also very important to understand that SLCN can be a symptom of, or co-occur with, other conditions such as:  
  • Autism Spectrum Condition (ASC). 
  • Hearing impairment. 
  • Learning disabilities. 
  • Intellectual disability. 

Key Considerations: 

• SLCN is a spectrum, and individuals can experience a wide range of difficulties. 
• Assessment and diagnosis should be conducted by qualified speech and language therapists. 
• It is important to remember that some children will present with SLCN, but will not have a formal diagnosis. 

Social, Emotional and Mental Health 

"Social, Emotional, and Mental Health" (SEMH) is a broad category used in education to describe a range of needs, rather than a list of strict medical diagnoses. However, certain diagnoses and conditions commonly fall under this umbrella. Here's a breakdown: 

Common Diagnoses and Conditions Associated with SEMH: 

• Anxiety Disorders:  
  • Generalized anxiety disorder (GAD) 
  • Social anxiety disorder 
  • Separation anxiety disorder 
  • Panic disorder 
  • Phobias 
• Mood Disorders:  
  • Depression 
  • Bipolar disorder 
• Attention-Deficit/Hyperactivity Disorder (ADHD):  
  • While ADHD also has cognitive aspects, it significantly impacts emotional regulation and social interactions. 
• Conduct Disorders:  
  • Oppositional defiant disorder (ODD) 
  • Conduct disorder (CD) 
• Attachment Disorders:  
  • Reactive attachment disorder (RAD) 
  • Disinhibited social engagement disorder 
• Trauma-Related Disorders:  
  • Post-traumatic stress disorder (PTSD) 
• Eating Disorders:  
  • Anorexia nervosa 
  • Bulimia nervosa 
• Other Conditions:  
  • Self-harm 
  • Emotional dysregulation 
  • Social communication difficulties (sometimes overlapping with ASC) 

Key Considerations: 

• SEMH is a spectrum: The severity and presentation of these difficulties vary widely. 
• Co-occurring conditions: It's common for individuals to experience multiple SEMH challenges simultaneously. 
• Environmental factors: Social and environmental factors, such as trauma, abuse, or neglect, can significantly contribute to SEMH needs. 
• Educational Context: In educational settings, SEMH focuses on how these difficulties impact a child's ability to learn and engage in school. 

Therefore, while there are specific diagnoses, SEMH encompasses a wide range of emotional and behavioural challenges that require support. 

Moderate Learning Difficulty 

When discussing Moderate Learning Difficulties (MLD), it's essential to remember that MLD itself is an educational descriptor, not a medical diagnosis. It signifies a level of need. However, certain underlying conditions can contribute to or be associated with MLD. Here's a breakdown: 

Difficulties Typically Associated with MLD: 

• Difficulties with Academic Skills:  
  • Struggles with reading, writing, and numeracy. 
  • Slower pace of learning. 
  • Challenges with understanding and applying learned concepts. 
  • Difficulties with memory and information processing. 
• Difficulties with Cognitive Function:  
  • Challenges with problem-solving and reasoning. 
  • Difficulties with attention and concentration. 
  • Slower cognitive processing speed. 
• Difficulties with Social and Adaptive Skills:  
  • Challenges with social interaction and communication. 
  • Difficulties with independent living skills. 
  • Challenges with understanding social cues. 

Diagnoses That Can Contribute to MLD: 

• Genetic Syndromes:  
  • Down syndrome (often associated with varying degrees of intellectual disability, including MLD). 
  • Fragile X syndrome. 
• Neurodevelopmental Conditions:  
  • Autism Spectrum Disorder (ASD): Some individuals with ASD may also experience MLD. 
  • ADHD: Can contribute to learning difficulties due to challenges with attention and executive function. 
• Acquired Brain Injuries:  
  • Brain injuries resulting from accidents or illnesses can lead to cognitive impairments and MLD. 
• Foetal Alcohol Spectrum Disorders (FASDs):  
  • Exposure to alcohol during pregnancy can cause a range of developmental and learning difficulties. 
• Other Factors:  
  • Environmental factors, such as early childhood deprivation or lack of stimulation, can also impact cognitive development. 

Important Considerations: 

• The severity of MLD can vary significantly. 
• Individuals with MLD may also have co-occurring conditions. 
• A comprehensive assessment is essential to determine the individual's specific needs and provide appropriate support. 

Severe Learning Difficulty 

When discussing "Severe Learning Difficulties" (SLD), it's crucial to understand that this term describes a level of educational need, indicating significant intellectual impairment. It's not a singular medical diagnosis. However, several conditions are commonly associated with SLD. Here's a breakdown: 

Key Characteristics of SLD: 

• Significant difficulties in understanding, learning, and remembering new information. 
• Challenges with basic skills like reading, writing, and numeracy. 
• Difficulties with everyday tasks and independent living skills. 
• Often requires lifelong support. 

Conditions Associated with SLD: 

• Genetic Conditions:  
  • Severe Down Syndrome: This genetic condition often results in significant intellectual disability. 
  • Other Chromosomal Abnormalities: Various rare genetic syndromes can lead to profound cognitive impairment. 
• Neurological Conditions:  
  • Severe Cerebral Palsy: When accompanied by significant brain damage, cerebral palsy can cause SLD. 
  • Acquired Brain Injuries: Severe brain injuries from accidents or illnesses can result in SLD. 
  • Certain Neurodegenerative Disorders: Some progressive neurological conditions can lead to severe cognitive decline. 
• Developmental Conditions:  
  • Severe Autism Spectrum Disorder (ASD): In some cases, ASD can be accompanied by significant intellectual disability, leading to SLD. 
  • Profound and Multiple Learning Disabilities (PMLD): This category involves SLD alongside significant physical or sensory impairments. 
• Prenatal Factors:  
  • Foetal Alcohol Syndrome (FAS): Severe FAS can cause significant intellectual disability. 

Important Considerations: 

• SLD is a spectrum: The severity of learning difficulties can vary. 
• Co-occurring conditions: Individuals with SLD may also have other health conditions, such as epilepsy or sensory impairments. 
• Assessment: A comprehensive assessment by professionals, including educational psychologists and medical specialists, is essential for accurate diagnosis and support planning. 
• It is vital to understand that the focus is on the individual’s needs, and the support they require, rather than simply the diagnosis. 

Specific Learning Difficulty 

Specific Learning Difficulties (SpLDs) are a group of conditions that affect a person's ability to learn and use certain academic skills. They are neurodevelopmental in origin, meaning they are related to how the brain processes information. Here's a list of common SpLDs, along with the difficulties and diagnoses associated with each: 

1. Dyslexia: 

• Difficulties:  
  • Reading accuracy and fluency. 
  • Spelling. 
  • Phonological awareness (understanding the sounds of language). 
  • Decoding words.

  • Understanding and using spoken language. 
  • Vocabulary development. 
  • Grammar and syntax. 
  • Verbal memory. 
  • Can impact reading and writing skills. 
  • Diagnosis: Developmental Language Disorder (DLD) or Specific Language Impairment (SLI). 

Important Considerations: 

• SpLDs often co-occur. For example, a person may have dyslexia and dysgraphia. 
• These are neurological differences, not intellectual disabilities. 
• Early identification and intervention are crucial for supporting individuals with SpLDs. 
• Individualised education plans (IEPs) or EHCPs are often necessary to provide appropriate accommodations and support. 
• It is worth noting that Auditory processing disorder, and visual processing disorder can also be considered to be SpLD's by some professionals. 

Physical Disability 

Physical disabilities encompass a wide range of conditions that affect a person's mobility, motor skills, and physical functioning. Here's a list of difficulties and diagnoses that typically fall under this category: 

Difficulties: 

• Mobility Impairments:  
  • Difficulty walking or moving independently. 
  • Reliance on mobility aids (e.g., wheelchairs, crutches, walkers). 
  • Limited range of motion. 
  • Muscle weakness or paralysis. 
  • Balance and coordination problems. 
• Motor Skill Difficulties:

Important Notes: 

• The severity of these conditions can vary greatly. 
• Many individuals with physical disabilities also experience co-occurring conditions, such as learning disabilities or mental health challenges. 
• It is also important to remember that many people with physical disabilities live full and active lives. 

Profound & Multiple Learning Difficulty 

Profound and Multiple Learning Difficulties (PMLD) represent the most complex and severe form of learning disability. Individuals with PMLD have significant challenges across multiple areas of development. Here's a breakdown of the difficulties and diagnoses typically associated with PMLD: 

Core Difficulties: 

• Profound Intellectual Disability:  
  • Very limited cognitive abilities, significantly impacting all areas of learning. 
  • Difficulty processing and understanding information. 
  • Limited or no ability to use symbolic communication. 
• Multiple Severe Disabilities:  
  • Significant physical disabilities, such as cerebral palsy, affecting mobility, posture, and coordination. 
  • Severe sensory impairments, including visual and hearing impairments. 
  • Complex health needs, requiring ongoing medical care. 
  • Epilepsy. 
• Communication Difficulties:  
  • Little or no spoken language. 
  • Reliance on non-verbal communication, such as facial expressions, body language, or gestures. 
  • Difficulties understanding and responding to communication. 
• Sensory Processing Difficulties:  
  • Hypersensitivity or hyposensitivity to sensory stimuli. 
  • Difficulties processing and integrating sensory information. 
• Health Needs:  
  • Many people with PMLD have very complex health needs. 

Diagnoses Often Associated with PMLD: 

It's important to reiterate that PMLD is a description of need, not a diagnosis itself. However, it's often associated with the following underlying conditions: 

• Severe Genetic Syndromes:  
  • Severe forms of Down syndrome. 
  • Other rare genetic conditions that cause profound intellectual and physical disabilities. 
• Severe Neurological Impairments:  
  • Severe cerebral palsy. 
  • Significant brain injuries acquired at birth or in early childhood. 
  • Congenital brain malformations. 
• Metabolic Disorders:  
  • Rare metabolic conditions that affect brain development and function. 
• Congenital Infections:  
  • Conditions caused by infections during pregnancy that impact development. 

Key Considerations: 

• Individuals with PMLD require highly specialised support across all areas of their lives. 
• A multidisciplinary approach involving healthcare professionals, therapists, and educators is essential. 
• The focus is on providing person-cantered care that maximizes quality of life and promotes well-being. 
• The level of need is the key factor, not the specific diagnosis. 

Other Difficulty / Disability 

This appears to be a bit of a grey area. There seems to be confusion with Local Authorities using this this as a definition. It could just be: 

• An LA doesn’t know what else to put. 
• Hasn’t filled in the consensus form properly. 
• There are multiple SEN needs that are not considered PMLD. 
• There are other difficulties / disabilities that do not fit in to the other categories. 

Hearing Impairment 

Diagnoses Related to Hearing Impairment: 

• Sensorineural Hearing Loss:  
  • Damage to the inner ear (cochlea) or the auditory nerve. 
  • Can be congenital (present at birth) or acquired. 
  • Causes include genetic factors, infections, noise exposure, and aging. 
• Conductive Hearing Loss:  
  • Problems with the outer or middle ear that prevent sound from reaching the inner ear. 
  • Common causes include earwax build-up, ear infections (otitis media), and problems with the eardrum or ossicles. 
• Mixed Hearing Loss:  
  • A combination of sensorineural and conductive hearing loss. 
• Auditory Processing Disorder (APD):  
  • Difficulties processing auditory information, even with normal hearing sensitivity. 
  • Challenges with understanding speech in noisy environments, following complex instructions, and discriminating between similar sounds. 
• Tinnitus:  
  • Perception of ringing, buzzing, or other sounds in the ears or head. 
  • Can be associated with hearing loss or other medical conditions. 
• Hyperacusis:  
  • increased sensitivity to certain frequencies and volume ranges of sound. 
• Specific Genetic Syndromes:  
  • Certain genetic syndromes, such as Usher syndrome and Waardenburg syndrome, are associated with hearing loss. 
• Otitis Media:  
  • Inflammation of the middle ear. Very common in children, and if recurring can cause hearing loss. 

Visual Impairment 

Visual impairment encompasses a wide range of conditions affecting eyesight, and the diagnoses associated with it are equally diverse. Here are some of the most common diagnoses that fall under the umbrella of visual impairment: 

Conditions Affecting the Eye Itself: 

• Congenital Cataracts: Clouding of the lens present at birth. 
• Glaucoma: Damage to the optic nerve, often due to increased pressure within the eye. Can be congenital or acquired. 
• Retinopathy of Prematurity (ROP): Abnormal blood vessel development in the retina of premature infants. 
• Retinitis Pigmentosa (RP): A group of inherited disorders that gradually damage the retina. 
• Macular Degeneration: Deterioration of the macula, the central part of the retina. 
• Diabetic Retinopathy: Damage to the blood vessels in the retina caused by diabetes. 
• Optic Atrophy: Damage to the optic nerve. 
• Corneal Dystrophies: Inherited conditions that affect the cornea. 
• Strabismus (Crossed Eyes): Misalignment of the eyes. 
• Amblyopia (Lazy Eye): Reduced vision in one eye due to abnormal visual development. 
• Nystagmus: Involuntary, repetitive eye movements. 

Conditions Affecting the Visual Pathway/Brain: 

• Cortical Visual Impairment (CVI): Visual impairment caused by damage to the parts of the brain that process vision. 
• Optic Nerve Hypoplasia: Underdevelopment of the optic nerve. 
• Brain Tumours: Tumours that affect the optic nerve or visual processing areas of the brain. 

Other Related Conditions: 

• Albinism: A genetic condition that affects the production of melanin, which can lead to visual impairments. 
• Oculocutaneous Albinism: albinism that affects the eyes, skin and hair. 
• Genetic Syndromes: Many genetic syndromes, such as Down syndrome and Leber congenital amaurosis, can be associated with visual impairments. 
• Traumatic Brain Injury (TBI): Can lead to visual impairments depending on the area of the brain affected. 
• Infections: Infections such as toxoplasmosis or cytomegalovirus (CMV) can cause visual impairments. 

Important Notes: 

• Visual impairment can range from mild to profound blindness. 
• Early diagnosis and intervention are crucial for maximizing visual potential and preventing further vision loss. 
• Visual impairments can be congenital (present at birth) or acquired later in life. 
• It is very important to note that many of these conditions can coexist. 

When considering visual impairment, it is essential to have a thorough examination by an ophthalmologist or other qualified eye care professional. 

Multi- Sensory Impairment 

Multi-sensory impairment (MSI), also known as deafblindness, involves a combination of hearing and visual impairments.1 It's not a single diagnosis, but rather a description of a combination of sensory losses.2 Several diagnoses can lead to MSI: 

Conditions Directly Causing Combined Hearing and Visual Loss: 

• Usher Syndrome:  
  • This is the most common genetic cause of deafblindness. 
  • It involves hearing loss (sensorineural) and retinitis pigmentosa (RP), a progressive eye disease that causes gradual vision loss.4 
  • There are different types of Usher syndrome, varying in the severity and progression of hearing and vision loss.5 
• CHARGE Syndrome:  
  • This is a complex genetic syndrome that can cause a range of birth defects, including coloboma (eye defect), heart defects, atresia of the choanae (blocked nasal passages), retarded growth and development, genital abnormalities, and ear abnormalities (including hearing loss) 
• Congenital Rubella Syndrome:  
  • If a pregnant woman contracts rubella (German measles), it can cause severe birth defects in the baby, including hearing and vision loss.
• Mitochondrial Disorders:  
  • These are genetic disorders that affect the mitochondria, the powerhouses of cells.8 They can cause a variety of symptoms, including hearing and vision loss. 

Conditions That Can Indirectly Lead to MSI: 

• Premature Birth:  
  • Premature babies are at increased risk of both hearing and vision problems, such as retinopathy of prematurity (ROP) and hearing loss due to complications. 
• Cerebral Palsy:  
  • While not directly causing hearing or vision loss, cerebral palsy can be associated with sensory impairments due to brain damage. 
• Traumatic Brain Injury:  
  • Brain injuries can affect both hearing and vision. 
• Certain Genetic Syndromes:  
  • There are many genetic syndromes that can have combinations of hearing and visual loss as a symptom. 

Important Considerations: 

• MSI is a spectrum, and the severity of hearing and vision loss can vary greatly. 
• Early identification and intervention are crucial for supporting individuals with MSI. 
• A multidisciplinary approach is essential, involving audiologists, ophthalmologists, therapists, and educators. 
• It is very important to understand that the combination of hearing and visual loss creates a unique disability, and that the interaction of the two losses, is greater than the sum of the individual parts. 

Therefore, while Usher syndrome is the most common cause, a range of other conditions can contribute to multi-sensory impairment.
