Audio-induced psychogenic non-epileptic seizures.

ABSTRACT

A 45-year-old woman presented with vague attacks, which consisted of headaches, confusion and sleepiness. An electroencephalograph was normal, but subsequent scans revealed the presence of a right-sided convexity meningioma. This was excised and complications led to the removal of an infected bone flap in a separate procedure the following year. Various types of 'seizures' resulted from the operation. These were described to involve both tonic-clonic and absence seizures. This continued for 18 years, unaffected by medication, until a specialist diagnosed pseudo-epilepsy, by fortune of a hospital fire alarm. The patient began a psychological intervention programme including cognitive-behavioural therapy, which has significantly reduced episodes. In conclusion, psychogenic non-epileptic seizures may develop after intracranial neurosurgery undertaken for indications other than the control of refractory epileptic seizures. A diagnosis of psychogenic non-epileptic seizures should be considered in patients who develop refractory seizures after neurosurgery and managed appropriately.
