How is Doose Syndrome diagnosed?

Doose Syndrome, also known as Myoclonic Atonic Epilepsy (MAE), is primarily diagnosed through a combination of clinical observation of seizure types and specific findings on an electroencephalogram (EEG). Because there is no single blood or genetic test to confirm the condition, diagnosis relies on a pediatric neurologist or epileptologist identifying the characteristic pattern of myoclonic-atonic seizures during early childhood development.

How is Doose Syndrome diagnosed?

The diagnostic process for Doose Syndrome is often a challenging journey because the condition can mimic other forms of childhood epilepsy. A specialist physician will typically begin by taking a detailed clinical history, focusing on the onset of seizures, which usually occurs between 7 months and 6 years of age. Diagnosis is confirmed through a clinical assessment of seizure semiology (the specific characteristics of the seizures) and the results of a video-EEG, which is the gold standard for identifying the unique electrical patterns associated with Doose Syndrome.

What tests and examinations are involved?

While there is no single diagnostic "marker" for Doose Syndrome, clinicians utilize a battery of tests to rule out other conditions and confirm the diagnosis:

• Video-EEG: This is the most critical tool. Doctors look for generalized spike-wave discharges, polyspike-wave complexes, and background slowing that correlate with the child's seizure activity.


• Genetic Testing: While Doose Syndrome is not caused by a single known gene, chromosomal microarrays or epilepsy gene panels are often ordered to rule out other genetic syndromes or metabolic disorders.


• MRI: Brain imaging is typically performed to ensure there are no structural abnormalities, tumors, or malformations that could be causing the seizures.


• Blood and Metabolic Panels: These are used to rule out secondary causes of epilepsy, such as electrolyte imbalances or metabolic conditions.

What is the typical diagnostic odyssey?

Many families in our DiseaseMaps community, which currently includes 65 members affected by Doose Syndrome, report a significant "diagnostic odyssey." Because Doose Syndrome is rare, it is frequently misdiagnosed initially as benign epilepsy with centrotemporal spikes or other childhood seizure disorders. It is common for parents to consult multiple physicians before receiving an accurate diagnosis. This delay is often due to the fluctuating nature of the seizures and the fact that Doose Syndrome can present differently in every child, making early recognition difficult for general practitioners.

Differential diagnosis: What else could it be?

Distinguishing Doose Syndrome from other conditions is vital for effective treatment. Doctors must differentiate it from Lennox-Gastaut syndrome, Dravet syndrome, and childhood absence epilepsy. Unlike some other syndromes, children with Doose Syndrome often have a normal developmental history before the onset of seizures, which is a key clinical clue for specialists. Seeking a pediatric epileptologist—a doctor who specializes in complex seizure disorders—is essential, as they are trained to recognize the subtle nuances that distinguish Doose Syndrome from more common forms of epilepsy.

Next steps

• Seek a referral to a board-certified pediatric epileptologist at a Level 4 Epilepsy Center.


• Maintain a detailed "seizure diary" recording the timing, duration, and specific movements observed during events to share with your specialist.


• Connect with the 65 members of the DiseaseMaps community to share experiences and find support during the diagnostic process.


• Ask your neurologist about the latest clinical literature regarding dietary therapies (such as the ketogenic diet), which are often used in the management of Doose Syndrome.
