R. Kan et al., ECHOGRAPHIA AS A SYMPTOM OF INTERICTAL STATE IN AN EPILEPTIC PATIENT - A CASE-REPORT, PSYCHIATRY AND CLINICAL NEUROSCIENCES, 51(1), 1997, pp. 27-30
Echographia is a phenomenon in which a patient continuously translates
verbal stimuli into writing. We encountered a patient with epilepsy w
ho developed visual echographia during interictal periods. In this cas
e, echographia was observed during two different periods, namely the p
eriod of disturbed consciousness after the epileptic seizure and the p
eriod of clear consciousness after suppression of the seizures. Disinh
ibition due to disturbance of the consciousness is considered to have
been the cause of echographia in the former period. In the latter peri
od, it is considered that echographia was caused by the release of low
er function from suppression of upper function by brain dysfunction, a
s the after effect of status epilepticus. As echographia can be observ
ed in epileptic patients, attention and careful observation by epilept
ologists is needed.
