Protecting wellbeing and supporting true participation: more research urgently needed

This page shares selected research on DEE-SWAS, EE-SWAS and related diagnoses including Landau-Kleffner syndrome (LKS), Continuous Spike-Wave in Sleep (CSWS) and Electrical Status Epilepticus in Sleep (ESES). It also includes broader epilepsy research and research from related fields that may help families make sense of changes in thinking, behaviour, emotions and identity, and support better child well being.

If you know of research to include, or if anything could be clearer, please email melanie@voicesofdeeswas.org

Definition of regression in childhood

A group of researchers developed a consistent definition of developmental regression to support better understanding of its causes, how commonly it occurs, and when investigations should take place, while promoting more consistent and standardised care.

The article is not specific to DEE-SWAS, but does discuss developmental and epileptic encephalopathies (DEEs). In DEE-SWAS and related diagnoses, developmental stagnation or regression is associated with activation of epileptiform activity during sleep that can affect cognition, language, behaviour and other areas of functioning.

Mental health of children with epilepsy in war

This study explores the mental health and epilepsy of children living through the war in Ukraine, including disrupted access to anti-seizure medication and medical care and increased seizure frequency for many children.

It was difficult to find research on the experiences of children with developmental and epileptic encephalopathies (DEEs), including the DEE-SWAS spectrum, living through war and displacement. Research exploring this, as well as the experiences of children who acquire epilepsy following conflict-related neurological injury, would be valuable.

School attendance the strongest predictor of health-related quality of life

When families talk about DEE-SWAS-related conditions, they often describe challenges that extend well beyond seizures. This 2026 study explored health-related quality of life and behavioural and emotional difficulties in 46 children and young people with DEE-SWAS and EE-SWAS. The findings suggest factors such as development, behaviour, communication and school participation may have a major influence on a child's day-to-day wellbeing and should be considered alongside seizure and EEG outcomes.

When autism is diagnosed after something changes

This paper looks at what happens when an autism diagnosis is given after a child changes over time.

It explores how differences in thinking, behaviour and social communication can emerge after something else has happened, and how these changes are sometimes understood through an autism diagnosis. While this paper focuses on acquired brain injury and not DEE-SWAS, the diagnostic journey outlined in the Zenah epilepsy case study may be relatable to some families.

Supporting students with changing needs

This paper looks at how children with traumatic brain injury (TBI) manage at school. TBI is caused by an external injury to the brain and is different to DEE-SWAS, which is driven by epileptic activity during sleep.

The paper focuses on changes in thinking, behaviour and emotions, and how these affect learning and everyday school life. While the cause is different, some of these challenges may feel familiar.

How brain changes shape identity, participation and everyday life

This paper presents a model for supporting children and young people after acquired brain injury (ABI). ABI is caused by an injury to the brain and is different to DEE-SWAS, which is driven by epileptic activity during sleep.

The paper focuses on identity, and how a child’s sense of self shapes their ability to engage in recovery, learning and everyday life.

“Complicated epilepsy” linked to higher support needs at school

This study looked at learning and school outcomes in children with early onset epilepsy, with a focus on those with “complicated epilepsy”, who have additional brain, developmental or cognitive difficulties. Conditions like DEE-SWAS would sit within this more complex group.

Intelligence Outcomes After Remission of DEE-SWAS

This study explored what happens to children’s intelligence after the abnormal sleep EEG pattern in DEE-SWAS resolves, examining whether cognitive abilities recover, stabilise, or continue to decline over time.
