Neurodevelopmental effects

Development, learning and behaviour

Alongside the physical effects, Fetal Anti-Convulsant Syndrome can affect a child's development, learning, communication, and behaviour. These effects vary from one individual to another, and not every child is affected in the same way.

A child exposed to valproic acid may be at a higher risk for learning and behavioural problems, which include ADHD and Autism.

Neurodevelopmental characteristics

Neurodevelopmental characteristics that may be seen include:

• Developmental delay
• Social Communication Disorder
• Autism Spectrum Disorder (ASD)
• Attention Deficit Hyperactivity Disorder (ADHD)
• Speech and language needs

Thinking and learning

Cognitive development can be delayed, and while children with FVSD keep learning new skills, they often function below age-expected levels. Common differences include a shorter attention span, slower processing of information, holding less in mind at once, and difficulties with executive function — getting started on and finishing tasks, being organised, and planning. Formal assessment is important, so that difficulties are not simply assumed to be due to autism or another diagnosis.

Sensory processing

Some people are slower to notice signals from their body or environment — such as hunger, pain, emotions, or needing the toilet — while others are highly sensitive to noise, movement or touch and can become easily overwhelmed. Calming strategies, quiet spaces, noise-cancelling headphones, and planned prompts can all help.

Mental health

There is an increased risk of anxiety (social or more general), low mood, and differences in regulating emotions. A referral to a mental health team should be considered when emotional health is affecting daily life — and it is important that cognitive and language needs are assessed first, so support is pitched at the right level.

Support and assessment

Although there is no cure for FACS or FVSD, many of the possible signs and symptoms do have treatments or therapies available, and early intervention can make a real difference. A neuropsychological assessment can identify learning or behavioural difficulties — see Risks & Diagnosis for when this is recommended.

In education and the workplace, reasonable adjustments under the Equality Act 2010, flexible timetables for appointments, written step-by-step instructions, extra time, and regular breaks can make a significant difference.
