That is caused by irritation or injury to specific areas of the brain by the tumor.   BEHAVIORAL CHANGES: Common behavioral changes include changes in judgment, reasoning, behavior; impaired memory; emotional changes such as rapid mood shifts; and confusion. Those symptoms are caused by edema and increased intracranial pressure. ..."
