It is a motivational disorders ...

This is a motivational disorders due to violation of relations cingulate gyrus and the limbic system. It is well known as the instability of the external passion, that is connected with excessive mobility of voluntary attention and criticism as a result of reduced dysfunction of the orbitofrontal cortex [1013, 45]. Along with biological preconditions for depression in frontal dysfunction, also play an undeniable role of psychogenic factors. Certainly, the experience of its growing intellectual and, as a rule, motor failure contributes to the formation of depressive disorders, at least in the early stages of dementia, in the absence of significant decrease of criticism. The presence of emotional disorders can worsen the severity of cognitive impairment due to higher levels of anxiety and related difficulties concentrating, uncertainty and expectations of failure. Thus, the relationship of cognitive and emotional disorders are quite complex. Both types of mental disorders linked the presence of common pathogenetic factors (the phenomenon of separation and frontal dysfunction), but also capable of directly affect each other in the above-described psychological mechanisms [16]. Clinical features of cognitive impairment in the ED Because the pathogenesis of cognitive impairment in the ED is heterogeneous, the clinical manifestations of intellectual deficit also mixed. However, leading in most cases is a syndrome of subcortical dementia or cognitive preddementnyh rasstroytsv. The pathogenesis of this type of cognitive impairment associated with lesions of the deep divisions of white and gray matter of the brain on the above pathological mechanisms. The term subcortical dementia was first proposed by M. Albert et al. in 1974 to refer to cognitive impairment in progressive paralysis nadyadernom [21]. In the future, similar cognitive disorders described in other neurological diseases: Parkinson's disease, vascular dementia, multiple sclerosis and other disorders of the deep cerebral structures. The term itself is not entirely successful, since an important role in the pathogenesis of subcortical ? ? cognitive disorders is dysfunction of the frontal cortex. Nevertheless, the term took from a clinical point of view and is widely used in the literature [26,40,49]. Subcortical dementia characterized primarily bradyphrenia bradifreniey: the patient requires more than normal time, and attempts to solve the pressing intellectual challenges. Insufficiency of short-term memory with relative preservation of long-term. This svoebrazie mental disorders leads to preservation of the memory of the events of life when expressed difficulties in learning, while simultaneously working with multiple sources of information and in solving multi-step tasks you want to save memory on the interim results of operations.? subcortical dementia ? characterized as a violation of perception and motor expression of spatial relationships, which manifests itself in the design and illustration.
