An 83-year-old woman was referred to hospital with a 2-week history of short-lived episodic unpleasant sensations in her head and running down her body. This was accompanied by new short-term memory impairment and arm spasms. Initial investigations including blood tests and brain imaging did not reveal the diagnosis. The patient developed an increasing frequency of abnormal movements of her face and arm. These were clinically recognised as faciobrachial dystonic seizures (FBDS). FBDS are pathognomonic of an autoimmune encephalitis caused by an antibody directed against leucine-rich glioma-inactivated 1 (LGI1). The clinical diagnosis resulted in treatment with immunotherapy, leading to cessation of seizures and rapid cognitive recovery. Later, the predicted serology was confirmed. This reversible and under-recognised cause of cognitive impairment, typically affecting elderly patients, can be diagnosed clinically to enable early and effective treatment.

A double-blind trial to determine the effects of a single dose of 2 mg benzhexol on cognitive functioning was undertaken using normal volunteers. Ninety minutes after the drug or placebo was taken, subjects completed a battery of psychological tests designed to measure learning, memory and motor skills. Benzhexol ingestion was associated with significant impairment of short-term memory and slowing of the rate of new learning.
