Michael Hunter

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
