[Cognitive impairment in multiple system atrophy - exclusion criteria or an integral part of the clinical picture?].

Multiple system atrophy (MSA) is a severe, orphan disease characterized by a steady increase in symptoms of parkinsonism, cerebellar disorders, and autonomic failure. In addition to autonomic failure, which is considered the defining symptom of this type of atypical parkinsonism, there are a range of other non-motor clinical manifestations, such as sleep disorders, pain syndrome, anxiety-depressive disorders, cognitive impairment (CI). CI, especially severe CI, has long been considered as a distinctive feature of MCA.

[Mechanisms of development of constipation in Parkinson's disease and therapeutic approaches].

Constipation is one of the most common non-motor symptoms of Parkinson's disease. The pathogenetic mechanisms of constipation, diagnostic criteria, approaches to investigations and treatment are discussed in the paper.

Genetic Markers as Risk Factors for the Development of Impulsive-Compulsive Behaviors in Patients with Parkinson's Disease Receiving Dopaminergic Therapy.

Impulsive-compulsive and related behavioral disorders (ICD) are drug-induced non-motor symptoms of Parkinson's disease (PD). Recently research has focused on evaluating whether ICD could be predicted and managed using a pharmacogenetic approach based on dopaminergic therapies, which are the main risk factors. The aim of our study was to evaluate the role of candidate genes such as , , , , , , , , gene polymorphisms in the pathogenesis of ICD in PD.

[A rare clinical case of comorbidity of early-onset Parkinson's disease and remitting multiple sclerosis].

Comorbidities of extrapyramidal disorders and multiple sclerosis (MS) are rare. The chance of a combination of MS and Parkinson's disease (PD) is less than 1 in 12.5 million.

[Creativity in patients with Parkinson's disease].

In some cases, a variety of creative abilities appear in patients with Parkinson's disease receiving dopaminergic therapy. These are the creativity of thinking, unusual motivation and efficiency, which are not inherent to the patients before. The author considers a spectrum of these changes, as well as their possible pathobiochemical and pathophysiological basis.
