<s>[INST] What are the effects of stroke? [/INST] The brain is an extremely complex organ that controls various body functions. If a stroke occurs and blood flow cannot reach the region that controls a particular body function, that part of the body won’t work as it should.

If the stroke occurs toward the back of the brain, for instance, it’s likely that some disability involving vision will result. The effects of a stroke depend primarily on the location of the obstruction and the extent of brain tissue affected.

The effects of a stroke depend on several factors, including the location of the obstruction and how much brain tissue is affected. However, because one side of the brain controls the opposite side of the body, a stroke affecting one side will result in neurological complications on the side of the body it affects.

Left Brain

If the stroke occurs in the left side of the brain, the right side of the body will be affected, producing some or all of the following:

Paralysis on the right side of the body
Speech/language problems
Individual’s behaviour is slow and cautious
Memory loss
Right Brain

If the stroke occurs in the right side of the brain, the left side of the body will be affected, producing some or all of the following:

Paralysis on the left side of the body
