The neurophysiological basis of psychiatric disorder is . for the most part, unknown. Though the relationship between the dysfunction of basal ganglia and psychiatric disorders is also unknown, the possibility is also unknown, the possibility is
confirmed by many researchers. The suggestion is that the basal ganglia, acting as an active sensory modulating station. maintain the normal flow of information processing. The dysfunction of the basal ganglia have been implicated in many
psychiatric
symptoms such as mood disturbance, delusion, hallucination, motor disorder and hypersensitivity.
Recently many brain imaging studies, using Positron emission tomography(PT). Single photon emission computed tomography(SPECT) and Magnetic resonance imaging(MRI) are being done eagerly trying to confirm the funtional and anatomical changes of
various
brain region including basal ganglia in vivo.
The authors experienced two cases of psychiatric inpatients with basal ganglia lesion detected in computed tomography(CT) scan incidentaly. One showed major depression like symptoms and the other showed schizophrenia-like symptoms. The authors
reported
two cases with literature review related to basal banglia in psychiatry.
