Global developmental delay-neuro-ophthalmological abnormalities-seizures-intellectual disability syndrome (GDNOS) is a rare genetic disorder characterized by global developmental delay, neuro-ophthalmological abnormalities, seizures, and intellectual disability. It is caused by a mutation in the gene encoding the transcription factor FOXG1.

The symptoms of Global Developmental Delay-Neuro-Ophthalmological Abnormalities-Seizures-Intellectual disability Syndrome (GDNOSIS) include:

-Delayed or absent milestones in physical, cognitive, and social development
-Delayed or absent language development
-Impaired motor skills
-Impaired visual and/or auditory processing
-Impaired social interaction
-Impaired communication
-Impaired problem-solving skills
-Impaired memory
-Impaired attention and concentration
-Impaired executive functioning
-Seizures
-Abnormal EEG patterns
-Abnormal eye movements
-Abnormal head size
-Abnormal facial features
-Abnormal muscle tone
-Abnormal reflexes
-Abnormal gait
-Intellectual disability

There is no single cure for Global developmental delay-neuro-ophthalmological abnormalities-seizures-intellectual disability syndrome. Treatment is focused on managing the individual symptoms and providing support to the patient and their family. Medications may be prescribed to help manage seizures, and physical, occupational, and speech therapy may be recommended to help with developmental delays. Additionally, medications may be prescribed to help with behavioral issues, and counseling may be recommended to help with emotional and social issues.
