ICD-10 Criteria for Hebephrenic Schizophrenia
A form of schizophrenia in which affective changes are prominent, delusions and hallucinations fleeting and fragmentary, behaviour irresponsible and unpredictable, and mannerisms common. The mood is shallow and inappropirate and often accompanied by giggling or self-satisfied, self-absorbed smiling, or by a lofty manner, grimaces, mannerisms, pranks, hypochondriacal complaints, and reiterated phrases. Thought is disorganized and speech rambling and incoherent. There is a tendency to remain solitary, and behaviour seems empty of purpose and feeling. This form of schizphrenia usually starts between the ages of 15 and 25 years and tends to have a poor prognosis because of the rapid development of "negative" symptoms, particularly flattening of affect and loss of volition.
Sounds more like the epilepsy described in my other link to me, but I'm not a physician so YMMV.
