[Zonisamide induced tremor--report of two cases]

Abstract:
Zonisamide is a new antiepileptic drug which has a wide range of antiepileptic efficacy. This drug is becoming widely to be used for patients with refractory epilepsies. The author reports two patients who developed resting and postural hand tremor after administration of zonisamide. The tremor was confined to the upper extremities and was enhanced with the emotional stress. The tremor has 4-5 Hz frequency and was severe enough to disturb their daily activities. Mild cogwheel rigidity was seen, but neither akinesia nor gait disturbance was recognized. The symptoms disappeared completely after cessation of the drug. This side effect should always be kept in mind in the treatment with zonisamide.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
