Finally, it has been shown many of the affects towards emotion, cognition and behavior are highly dependent upon the hemispherical location of the lesions. Left-hemispherical lesions have a tendency to provoke slower decision times also with more mistakes, depression, anxiety, apathy and certain emotional deficits such as: emotional inhibition and controlling of emotions. Right-hemispherical lesions have a tendency to provoke neglect, hemianopia, anosognosia, anxiety and depression, as well as emotional response and arousal. Depression is the most common deficit affecting up to 40% of stroke patients. As for which hemispherical location has the most drastic effect, I don’t believe there really is a difference because both sides have their own affects and they all are difficult changes to be dealing with. “There were 294 subjects […] registered in 1995, of which 101 (34.3%) were dead by three months after stroke” (Patel, Mehool; Coshall, Catherine; Rudd, Anthony G; Wolfe, Charles D.A., 2003, p.158).

Neglect or hemianopia, the loss of vision on one side of both visual fields, also highly influence the increase in reaction times, although predominantly in right hemisphere patients. Left-sided lesions are usually associated with memory deficits/dementia; but memories are stored in the inner part of the temporal lobe and, unless both the left and right lobes are damaged, memory loss after stroke is usually only temporary. On average, about 25% of all stroke patients will have no memory deficits and all other patients will – either alone or with other cognitive deficits. Most of the stroke patients who tend to have memory deficits though do appear to be much “older [and have] lower educational [levels as well as] more left sided lesions than patients with no memory deficits” (Ferro, J.M.; Guerreiro, M.; Madureira, S., 2001, p.624). Some cognitive deficits can also have a high influence on the behavioral problems of most stroke patients as well – one of high interest being anosognosia.
