At least three types of ictal atomic phenomena can be seen in partial seizures. Focal atomic seizures are partial seizures with ictal paresis or paralysis of one or more body parts preceding or independent of any convulsive activity. A diagnosis may be difficult without simultaneous EEG recording supplemented by video monitoring or polygraphy. Epileptic negative myoclonus manifests as brief lapses in tone in one or more muscle groups that interferes with motor coordination and postural control. Drop attacks can also occur in partial seizures, as have been well documented in patients with temporal or frontal lobe epilepsy. Different mechanisms may underlie these three phenomena. Focal atonic seizures probably result from relatively circumscribed seizure activity in one or more cortical areas that contribute to the elaboration and execution of motor functions. Whether this represents inactivation or interference in motor integration, or activation of inhibitory system, remains unresolved. The pathophysiology of epileptic negative myoclonus, like that of its positive counterpart, is probably to be found at a more local level, possibly from transiently enhanced local inhibition in the motor cortex. Drop attacks in partial seizures may be close in mechanism to that also seen in generalized seizures, possibly related to ictal activation of descending inhibitory pathways in the brainstem.

A 52-year-old man was admitted to our hospital due to drop attack accompanied with progressive right hand's clumsiness and recent memory impairment. Neurological examination revealed postural involuntary movement of the right hand, and impaired finger fine movements. He showed mild mental deterioration with lower MMSE score. Toreponema Pallidum Latex immuno Assay (TPLA) titers in serum and cerebrospinal fluid (CSF) were remarkably elevated. MRI revealed cerebral atrophy in the left hemisphere. The 99mTc-ECD SPECT analysis showed reduced cerebral blood flow in the left hemisphere. EEG showed slow background activity in the left hemisphere. Drop attacks and involuntary movement were diminished by the administration of the valproate. We diagnosed this case as Lissauer's general paresis and treated with intravenous benzylpenicillin potassium 24 million units per day for 2 weeks. After this treatment, the titer of TPLA in the serum and CSF decreased. The clinical symptoms and signs, the score of MMSE, findings of SPECT and EEG also improved. Although Lissauer's general paresis is a rare form of neurosyphilis, it is important to distinguish this disease in case of progressive dementia and focal neurological signs. Early diagnosis and treatment are the only way to prevent irreversible neurological damage in this disease.
