Paroxysmal alpha activity in Rett syndrome: a case report

Area of Science:

• Neuroscience
• Genetics
• Pediatrics

Background:

• Rett syndrome is a severe neurodevelopmental disorder affecting females, characterized by regression after initial normal development.
• Key features include loss of hand skills, hand stereotypies, speech loss, gait issues, and microcephaly.
• Epilepsy is common, affecting 70-90% of individuals with Rett syndrome, with known EEG abnormalities.

Observation:

• A case study of a 9-year-old girl with Rett syndrome and epilepsy revealed a unique electroencephalography (EEG) finding.
• This involved intermittent paroxysms of alpha activity observed during both wakefulness and sleep.
• Notably, these EEG findings were present without any accompanying clinical signs.

Findings:

• The observed EEG pattern of diffuse paroxysmal alpha activity is novel and has not been previously documented in the English literature.
• This unique signature represents a distinct electroencephalogram characteristic specific to Rett syndrome.

Implications:

• Recognizing this unique EEG pattern expands the known spectrum of electroencephalography abnormalities in Rett syndrome.
• This finding may aid in earlier or more accurate diagnosis and understanding of the neurological underpinnings of Rett syndrome.
• Further research into this specific EEG signature could offer new insights into Rett syndrome pathophysiology.
