  • Transient ischemic attack (TIA)
  • Side affects of medications that act on the central nervous system. For example, phenytoin, narcotics or carbamazepine

Home Care Remedies

For dealing with aphasia patients, family members may need to provide orientation reminders as many as possible. For example, they have to remind day of the week to the patient. Confusion and disorientation occur with aphasia. There is a general misconception that patients with aphasia are incompetent. However, caregivers and patients can sometimes implement nonverbal ways of communicating.

For dysarthria, using hand gestures and speaking slowly are suggested by therapists. Family and friends need to be patient and provide enough time for those with the disorder to express themselves. If possible you should stop the medications that are causing the speech impairment.

For people with severe speech impairment, it is very much important to recognise and treat depression.
