Angelman syndrome

Angelman syndrome is a rare genetic neurodevelopmental disorder that affects motor development, communication, and cognitive functioning. It is most commonly caused by abnormalities involving the UBE3A gene on chromosome 15.

The first signs usually appear during early childhood, when developmental delays and significant speech difficulties become noticeable. People with Angelman syndrome are often characterized by a cheerful disposition, frequent smiling, and a strong desire for social interaction, although verbal communication is typically limited.

Symptoms of Angelman Syndrome

Common symptoms include:

• delayed psychomotor development;
• severe speech impairment or absence of speech;
• balance and coordination difficulties;
• an unsteady, characteristic gait;
• frequent laughter, a happy demeanor, and increased sociability;
• attention deficits and hyperactivity;
• sleep disturbances;
• epileptic seizures, often beginning in early childhood.

The severity and combination of symptoms vary from person to person.

Therapy for People with Angelman Syndrome

Although there is currently no cure for Angelman syndrome, early diagnosis and comprehensive multidisciplinary therapy can significantly improve quality of life and support overall development.

Treatment commonly includes physiotherapy, occupational therapy, speech and language therapy, and augmentative and alternative communication (AAC). Depending on individual needs, neurological care and epilepsy management may also be required.

Psychological support and parent education are equally important components of care. A personalized therapeutic approach and close cooperation between healthcare professionals and the family help develop communication, independence, social skills, and everyday functioning.
