Frontal-complex partial status epilepticus misdiagnosed as bipolar affective disorder in a 75-year-old man.

The incidence and prevalence of epilepsy increases with age, with the majority of cases having a known cause, and approximately half of elderly patients with epilepsy experiencing complex partial seizures that often present initially as neuropsychiatric symptoms. This presentation often delays diagnosis of the epileptiform disorder. To illustrate, we present the case of a 75-year-old man who was initially misdiagnosed with bipolar affective disorder later to be revealed as a frontal lobe seizure disorder.

Epileptogenic action of tungstic acid gel on cat lumbar motoneurons.

Injection of tungstic acid gel (but not pH adjusted saline) into the cat lumbar ventral horn results in spontaneous, epileptiform activity consisting of waves of repetitive, high frequency, action potentials in motoneurons surrounding the injection site. In most motoneurons the action potentials are grouped in high frequency bursts composed of action potentials triggered from the delayed depolarization of the preceding action potential. The same kind of bursting can be triggered by intracellular current pulses, indicating that altered neuronal membrane properties are associated with the bursting activity. This type of bursting differs markedly from that seen in motoneurons during penicillin or strychnine-induced spinal seizures.
