Migralepsy

Migralepsy is a rare condition in which a migraine is followed, within an hour period, by an epileptic seizure. Because of the similarities in signs, symptoms, and treatments of both conditions, such as the neurological basis, the psychological issues, and the autonomic distress that is created from them, they individually increase the likelihood of causing the other. However, also because of the sameness, they are often misdiagnosed for each other, as migralepsy rarely occurs.

Signs and symptoms

General symptoms of migralepsy are:

Flashes of light

Geometric or animate forms

Visual hallucinations

Vomiting

Headache

Blindness

Loss of consciousness

Convulsions

Cause

The connection between migraines and epileptic seizures is currently being researched and not much is known. Patients have been shown to have had migraines long before developing epileptic symptoms, creating the possibility of severe cases of migraines creating epilepsy. However, not every migraine may be accompanied by a seizure and sometimes the seizures happen without any migraine involvement. Due to this, finding the origin of migralepsy is difficult and enveloped somewhere in the overlap between both conditions. Some patients have shown that their relatives had migraines as well and even some from migralepsy, forming the possibility that migralepsy is genetic in origin and forms only rarely as both, generally resulting in only one condition or the other.

Diagnosis

Because epileptic seizures may occur with a side effect that resembles migraine aura, it is complicated to diagnose whether a patient is having a normal epileptic episode or if it is a true migraine that is then being followed by a seizure, which would be a true sign of migralepsy. Many neurological symptoms can only be expressed by the patient, who can confuse different feelings, especially when the symptoms of a migraine are extremely similar to that of a seizure.
