Abstract:
Occipital lobes are not usually implicated in the current proposed pathways of pathological laughter.
We present a case of occasional pathological laughter associated with pontine infarct. Brain SPECT
revealed hypoperfusion of bilateral occipital lobes in addition to an underlying abnormal regulation
of the cortico-pontine-cerebellar pathway. The cause of bilateral occipital hypoperfusion was thought
to be due to vertebrobasilar stenosis in our patient. The co-existence of bilateral occipital lobe
hypoperfusion in our patient suggest that occipital lobes may also be involved in the generation of
pathological laughter.
