How do I know if I have Doose Syndrome?

Doose Syndrome, clinically known as Myoclonic-Atonic Epilepsy (MAE), is a rare childhood epilepsy syndrome typically beginning between 6 months and 6 years of age, characterized by various seizure types, most notably myoclonic-atonic "drop" seizures. Diagnosis is primarily based on clinical observation of specific seizure patterns and characteristic findings on an electroencephalogram (EEG), rather than a single definitive laboratory test.

What are the early signs and symptoms of Doose Syndrome?

The hallmark of Doose Syndrome is the sudden onset of seizures in an otherwise healthy, typically developing child. The most specific symptom is the myoclonic-atonic seizure, where a child experiences a brief muscle jerk followed immediately by a sudden loss of muscle tone, causing them to fall to the ground. Other seizure types often seen in patients with Doose Syndrome include generalized tonic-clonic seizures, absence seizures, and myoclonic jerks. It is important to note that before the onset of these seizures, children with Doose Syndrome usually show normal physical and cognitive development.

How do I know if my child should be evaluated for Doose Syndrome?

If your child is experiencing unexplained falls or sudden staring spells, it is crucial to document these events. You should look for specific patterns: are the falls associated with a brief jerk, or does the child simply "go limp"? Keep a video diary of these episodes, as visual evidence is often the most valuable tool for a neurologist. Parents of the 65 members on DiseaseMaps.org often report that the unpredictability of these "drop" seizures is what finally prompted them to seek an urgent specialist consultation.

What diagnostic tests are used to identify Doose Syndrome?

Because there is no single blood test for Doose Syndrome, physicians rely on a combination of clinical evaluation and diagnostic imaging. If you suspect your child has Doose Syndrome, you should request the following:

• Long-term Video EEG: This is the gold standard for identifying the characteristic generalized spike-wave discharges associated with Doose Syndrome.


• Neurological Examination: A comprehensive physical exam to rule out other structural or metabolic causes.


• Genetic Testing: While Doose Syndrome is not typically caused by a single gene mutation, genetic panels can help rule out other epileptic encephalopathies that may mimic its presentation.


• MRI of the Brain: Usually performed to ensure there are no structural brain abnormalities.

When should I seek urgent medical attention?

Certain symptoms require immediate emergency care. If your child experiences status epilepticus—a seizure lasting longer than five minutes—or has multiple seizures in rapid succession without recovering consciousness in between, take them to the nearest emergency department immediately. Furthermore, if you notice a sudden, rapid decline in cognitive or motor skills, or if the child becomes unresponsive for extended periods, do not wait for a routine appointment.

How can I advocate for my child if concerns are dismissed?

If a primary care provider dismisses your concerns as "normal clumsiness" or "benign childhood behaviors," you have the right to seek a second opinion from a board-certified pediatric epileptologist. Bring your video evidence and a written log of seizure frequency. Do not feel intimidated; you are the most observant expert regarding your child’s health. If you feel your concerns are not being heard, clearly state: "I am concerned that these episodes represent a seizure disorder and I would like a referral to a specialist to rule out an epilepsy syndrome."
