[Analysis of mental functions in patients after coronary bypass surgery].

The neuropsychological examination was carried out in 18 men (study group), mean age 59.7 +/- 6.6 years, before and after aorto-coronary bypass.

[The acute period of brain concussion: the dynamics of the clinical and neuropsychological symptoms].

Analysis of significant correlations between clinical and neuropsychological symptoms in 104 young patients with no anamnesis load, made in the acute period of brain concussion (BC), has demonstrated that the intensity of clinical symptoms correlates with the grade of disorders of higher mental functions (HMF). Besides, significant correlations were discovered between neuropsychological symptoms of brain stem injury and disorders of energy supply to HMF as well as between clinical symptoms of the involvement of the limbic-diencephalic structures and disorders of arbitrary control and emotional disturbances which are determined by the involvement into the pathological process of the anterior parts of the right and left cerebral hemisphere. The dynamic of clinical and neuropsychological symptoms after BC lies in the regression of disorders of stem nonspecific system, diencephalic and limbic structure functions.

[Visual-form thinking of patients before and after stereotaxic surgery on the ventrolateral nucleus of the thalamus].

An examination of patients with deformed muscular dystonia before and after stereotaxic surgery on the ventrolateral nucleus of the thalamus showed that prior to the surgery they had a certain difficulty in solving tasks involving mental manipulation with three-dimensional objects and constructive activity. It took them more time to accomplish these tasks and they made different mistakes as compared to normal. Changes in the object and image thinking differed, depending on the side of the destruction of the ventrolateral nucleus of the thalamus.
