Neurosyphilis has been known to present with wide array of neuropsychiatric
signs and symptoms. However little is known of the severity of its
manifestations especially in our Malaysia setting. We are reporting a case of
a middle-aged ex-military Malay man who contracted neurosyphilis during
active service and since then had severe neuropsychiatric symptoms which
caused deterioration in his activities of daily living skills which warrants
constant supervision. We discuss the various presentations of neurosyphilis
and its sequelae despite completion of antibiotics treatment.
