There are different effects when a stroke happens on the right side of the brain versus the left side of the brain. The most fundamental effect is that a stroke on the right side of the brain causes problems on the left side of the body, and a stroke on the left side causes problems on the right.
Generally speaking, right brain post-stroke side effects are:
Left-sided weakness
Impulsive behavior
Overconfidence in abilities
Vision problems
Generally speaking, left brain post-stroke side effects are:
Right-sided weakness
Speech and language problems
Slowed behavior
Common post-stroke side effects
Shoulder-hand syndrome. Muscles decrease in size and strength, causing the shoulder to slip out of its socket. Symptoms include tingling, varying feelings of hot and cold, and changes in sensation.
Learned non-use. The functional loss of one or more muscle groups on one side leads to only using "the good side". This can cause circulatory problems, muscle wasting, and skin breakdown on the affected side. It also increases the risk of injury or infection on the affected side.
Spasticity. Limbs change position and can become stiff, painful, or even shortened, limiting strength, mobility, and balance, and interfering with daily life.
Dysarthria. A collective term that describes several speech changes, including apraxia and aphasia. Aphasia can be especially frustrating.
Dysphasia. Difficulty swallowing can lead to malnutrition and aspiration (food and liquids passing into the lungs).
Cognitive impairment. Disruptions in mental processing are common among stroke survivors due to damage in parts of the brain that control communication, visual processing, memory, social skills, and attention span.
Depression. A frequent problem after a stroke resulting from the significant physical and psychological changes sustained.
