Rehabilitation Program
Physical Therapy
A small percentage of patients with a posterior cerebral artery (PCA) infarct suffer chronic motor deficits. Approximately 5% of patients who do may require transfer, gait, and stair training with an assistive device. Orthotic devices (eg, ankle-foot orthosis) also may be beneficial. Patients with PCA infarcts may demonstrate delayed postural reactions due to sensorimotor deficits. Programs designed to improve postural control and balance may be helpful. Home exercise programs and family/caregiver training are important to sustaining improvement after discharge from therapy.[19]
Occupational Therapy
The occupational therapist helps the patient adapt to homonymous hemianopia and visual-spatial function abnormalities. The patient benefits from scanning into the field deficit. A small percentage of patients who have suffered a posterior cerebral artery (PCA) stroke require therapy for motor deficits of the upper limb.
Speech Therapy
Speech therapy usually is not required for patients who have had a posterior cerebral artery (PCA) stroke. However, in infrequent cases in which there is neuropsychologic deterioration or memory-language deficits,[6] a speech therapist should be consulted. Although dysphagia typically is not associated with PCA infarcts, evaluation of swallowing may be useful in patients who may be at risk for aspiration.
Recreational Therapy
Recreational therapy helps patients with posterior cerebral artery (PCA) stroke to adapt to visual deficits and facilitates a healthy affect (since depression is a common occurrence in stroke patients).
Medical Issues/Complications
- Recurrent ischemic event[19]
- Hemorrhage into infarcted brain tissue
- Stroke-associated epilepsy
- Anticoagulation-associated intracranial, gastrointestinal, or retroperitoneal hemorrhaging
- Urinary tract and pulmonary infections
- Skin breakdown
- Depression
- Chronic pain
- Dyskinesia and dystonia
Consultations
- Ophthalmologists accurately plot visual-field loss in patients with posterior cerebral artery (PCA) stroke and can recommend corrective lenses and compensation techniques.
- Pain specialists treat rare intractable thalamic pain with many methods including anticonvulsants (carbamazepine [Tegretol], gabapentin [Neurontin]) and tricyclic medications (amitriptyline [Elavil]). Recently, topiramate (Topamax) has been found helpful in treating headache and painful dysesthesias.
- A psychiatrist may assist with treatment of mood disorders and psychotic symptoms.
- A neuropsychologist can help to assess and document cognitive function, which is especially important for persons returning to professional duties, considering living alone, or applying for disability.
Other Treatment
Many experimental treatment modalities such as cognitive retraining,[20] neuropharmacologic therapy (amphetamines),[21] robot-assisted physical and occupational therapy, and virtual environments[22] are reported to aid stroke recovery, but further evidence is needed to confirm their benefit.
In a single-blind cluster, randomized, controlled trial, stroke patients in acute stroke units (ASUs) were evaluated 90 days after hospital admission. ASUs were randomly appointed to intervention (n=10) or control (n=9). Those patients who received a multidisciplinary intervention focusing on evidence-based management of fever, hyperglycemia, and swallowing dysfunction were much less likely to be dead or dependent at 90 days, despite the severity of the stroke, compared with the control ASU patients.[23]
