Strangled by Dr Strangelove? Anarchic hand following a posterior cerebral artery territory ischemic stroke

Abstract

Anarchic hand is a rare condition where the complex movements of one hand appear to be goal directed and smoothly executed and yet are unintended and unwanted. Unlike alien hand syndrome, the patients recognise that the affected hand is part of their own body. They know the hand is theirs, but they deny having control over its actions. The syndrome has been reported after surgery on the corpus callosum and with brain tumours, aneurysms, degenerative diseases of the brain and uncommonly with stroke. We present a case of a 74-year-old man who developed an anarchic right hand following thrombolysis for a posterior cerebral artery territory ischemic stroke.
