Answer

Specific brain sites and associated deficits involved in hemorrhagic stroke include the following:

  • Putamen - Contralateral hemiparesis, contralateral sensory loss, contralateral conjugate gaze paresis, homonymous hemianopia, aphasia, neglect, or apraxia

  • Thalamus - Contralateral sensory loss, contralateral hemiparesis, gaze paresis, homonymous hemianopia, miosis, aphasia, or confusion

  • Lobar - Contralateral hemiparesis or sensory loss, contralateral conjugate gaze paresis, homonymous hemianopia, abulia, aphasia, neglect, or apraxia

  • Caudate nucleus - Contralateral hemiparesis, contralateral conjugate gaze paresis, or confusion

  • Brainstem - Quadriparesis, facial weakness, decreased level of consciousness, gaze paresis, ocular bobbing, miosis, or autonomic instability

  • Cerebellum – Ipsilateral ataxia, facial weakness, sensory loss; gaze paresis, skew deviation, miosis, or decreased level of consciousness
