63 year old Right Handed Male
Documented High Blood Pressure for several years
Prior history of Coronary Occlusion
Patient History
IncidentMorning attack of giddiness
and headache
Inability to read
Three days later developed
slight right hemiparesis
Neurological examination also
disclosed dysphasia and
Right-sided homonymous
hemianopia.
Signs of stroke1. Right-sided weakness (right hemiparesis)
2. Sensory impairment Speech Vision Numbness
Diagnosis: Left Hemispheric Stroke
Affected areas of the brain
• Reduced density involving the lower mesial region of the left occipital lobe• Possible inclusion of the hippocampus• Left Sylvain fissure and trigon were markedly enlarged• Decreased density was also apparent in the upper portion of the left• Cerebellar hemisphere
Sensory Deficits and their affects on the
patient Weakness on right side, right hemiparesis. a. Right-sided hemiparesis involves injury to the left side of
the person's brain, which is the side of the brain
controlling speech and language.
Dysphasiaa. Dysphasia, also referred to as Aphasia, is a partial or
complete impairment of the ability to communicate resulting from brain injury.
Right-side homonymous hemianopia
Homonymous hemianopia is a visual field
defect involving either the two right or the
two left halves of the visual fields of both
eyes. It is caused by lesions on the
opti-tract
("Homonymous Hemianopia", 2013)
Sensory Deficits and their affects on the
patient
Initial exam Loss of ability to form mental images Picture naming impaired Object naming normal He could identify the pictures he was not able to name
pointing to pictures as named by examiner Write single letters to dictation, but could not read8 out of
10 letters Reading of syllables and words was severely impaired with
45 and 80 errors respectively. The reading of meaningless words and of sentences was
impossible.
Loss of Mental Imagery
Follow up visit four months after incident Writing to dictation almost to normal Picture naming capabilities had improved, but only slightly.
He could name 11 pictures out of 20. Few, if any, errors in reading single letters and syllables Hesitant in reading words but he was 100% accurate In contrast, when reading meaningless words he was still
considerably impaired Incapable of reading sentences. All other modalities of mental imagery affected also. Patient
complained of no imagination of sounds, tastes, or smells
Loss of Mental Imagery
Rehabilitation from strokes
Physiatrists-doctors who specialize in rehabilitation. Physical therapists -are specialized in treating disabilities
related to large movement and can help with endurance, strength, and range of motion problems.
Occupational therapists –help people with daily living and fine motor skills
Rehabilitation and TherapyStrokes
Hemiparesis Rehabilitation Electrical Stimulation- placement of small electrical pads on the
muscles of the person's weakened limb and applying a small electrical charge to help the muscles contract as the person works to make it move.
Cortical Stimulation-electrical stimulation to the area of the brain called the cortex by placing a tiny electrode on the membrane covering the brain. The person performs rehabilitation exercises while the stimulation is given. (Left Hemispheric Stroke (2013)).
Rehabilitation and TherapyHemiparesis
Rehabilitation and TherapyDysphasia
Speech therapy can help
improve communication
Time helps the Dysphasic
sufferer recover to some
extent without any therapy
Many learn to Adapt to the
situation with slower
speech, repetition, or
using gestures, and
avoiding noisy areas
