Deteriorating Mental Status

Chapter 8 Deteriorating Mental Status


Lesions causing changes in mentation will be structural, metabolic, or toxic in origin. Clinical signs of diffuse cerebral disease with normal brain stem function are most common with metabolic disease, toxins, or drugs affecting the cerebrum globally (Boxes 8-1 and 8-2). Seizures indicate cerebral cortical dysfunction caused by either extracranial or intracranial disease (see Chapter 98, Seizures and Status Epilepticus). Impairment of the brain stem or thalamus, as well as lateralized cerebral dysfunction (e.g., compulsive circling in one direction, unilateral cortical blindness), is more likely the result of structural disease or injury (Box 8-3).
