Neurological problems and strokeMy father had a stroke which affected his left arm and leg. Although the power seems to have returned, he is still having problems looking after himself. It's almost as if he has forgotten that he has a left side. Is this normal?
The effects of a stroke can vary widely from one person to another. While a stroke may leave one person with a mild weakness, another may experience complete paralysis on one side of the body.
Strokes occur when there is a disruption to the blood supply to an area of the brain. As each area of the brain is responsible for different motor and sensory functions (see illustration) the resulting problems will depend greatly on the site and size of the area affected by the stroke. So not only may there be loss of power in the muscles but there may also be difficulties with speech, emotions and behaviour. Intellectual abilities, the sensation of pain, heat, cold and pressure, and awareness of body parts may also be affected. These and problems with spatial awareness and orientation can lead to difficulties in carrying out self care tasks and other activities of daily living.
Is this why he's ignoring his left side?
Yes. Inattention to one side of the body is often seen in those who have had a stroke affecting the parietal lobe in the brain. If your dad's muscles have recovered enough power to move his arm and leg and yet he neglects this side of his body when he dresses, shaves and performs other personal activities, then it sound like he's suffering from what is called "unilateral neglect".
Can this be treated?
Your dad would benefit from seeing an occupational therapist. They are trained to help individuals bridge the gap between what they can do and what they need to do to lead an independent life. They have a particular expertise in the area of sensory problems following a stroke or other neurological disability and will be able to devise a programme to encourage greater participation of the neglected side.
You should contact your local community care area office who should be able to put you in touch with the community occupational therapist Alternatively, you can contact the Association of Occupational Therapists in Ireland (AOTI) at www.aoti.ie
