Currently, studies aimed at assessing the emotional state and cognitive processes associated with the processing of emotionally determined information in patients with ischemic stroke, as well as finding the relationship between them are particularly relevant, mainly for the subsequent optimization of the therapeutic process. In order to identify the features of the emotional state and cognitive processes, a group of patients with ischemic stroke in the acute period in the amount of 25 people was examined. It was established that in patients with a lesion in the anterior cortex, depressive states in the acute period of stroke are more pronounced. Patients successfully reproduce emotionally significant words in comparison with neutral words; an interrelation between the level of anxiety and depression was found, which indicates that these states are comorbid. But, in turn, the relationship of the severity of anxiety and depression with the cognitive processes of recognition and reproduction, as well as differences in mnestic and gnostic activity in patients with different levels of anxiety and depression were not identified. After the treatment with Semax an improvement was noted.
