Prevalence clearly varies over time with an apparent peak 3–6 months after<unk>  and subsequent decline in prevalence at one-year reaches about to 50% of initial rates. Robinson and colleagues characterized the natural course of major<unk>  after<unk>  with spontaneous remission typically 1 to 2 years after<unk> . However, it was also noted that in few cases<unk>  becomes chronic and may persist more than 3 years following<unk> . On the other hand, minor<unk>  appeared to be more variable, with both short term and long term<unk>  occurring in these patients.<unk>  is highly prevalent among both men and women. However, it appears that<unk>  is more common in women when prevalence is compared between the sexes. Women were twice as likely to experience<unk>  than men. It is hypothesized, based on CT scanning, that of the two sexes experiencing<unk> , women who had<unk>  had a higher rate of left hemisphere lesions than men. However, risk of<unk>  can not be determined effectively based on the location of the lesion in the brain and more research in this area is needed. It has also been postulated that the risk of developing<unk>  in male patients is partly linked to having a high level of limitations and disability in functioning, especially in performing activities of daily living (ADL's), as a result of their<unk> ; the greater the limitation, the greater the severity. Risk of developing<unk>  post-stroke in women is partly linked to a history of psychological disorders as well as limitations involving cognition as a result of their<unk> .
