Parkinson's disease (PD) is diagnosed many years after its onset, under a significant degradation of the nigrostriatal dopaminergic system, responsible for regulation motor function. This explains low effectiveness treatment patients. Therefore, one highest priorities in neurology development early (preclinical) diagnosis PD. The aim this study was to search changes blood patients at risk developing PD, which are considered potential diagnostic biomarkers. Out 1835 patients, 26 were included...
Parkinson’s disease (PD) is diagnosed by the onset of motor symptoms and treated long after its onset. Therefore, development early diagnosis PD a priority for neurology. Advanced methodologies this include (1) searching patients at risk developing prodromal based on premotor symptoms; (2) changes in body fluids these as diagnostic biomarkers; (3) verifying diagnostic-value biomarkers using positron emission tomography (PET); (4) anticipating symptoms. According to our data, majority (n =...
An important approach to an early diagnosis of Parkinson's disease (PD) is screening for peripheral biomarkers in patients at the clinical stage.

The main treatment for cervical dystonia (CD) is botulinum toxin type A (BTA) injections, but several long-term studies have found that between 19-46% of patients discontinue treatment. Anxiety and depression play a signi fi cant role in reducing the quality life with CD, according to previous surveys. Aim: assess dynamics CD symptom severity, emotional disturbance, under different methods. Material 61 16 (26%) men 45 (74%) women, age 50 [40; 59] years, duration illness 4 [2; 7] at onset 44...
This review provides information onthe non-motor peripheral manifestations of Parkinsons disease (PD) associated with a pathology the visual analyzer and auxiliary apparatus eye. The relationship between neurodegenerative processes that take place in brain eye opens new prospects to use preventive ophthalmologic examination todiagnose PD long before characteristic motor symptoms appear. will encourage neuroprotective therapy, which stops, or at least slows down, neuronal death, instead...
Cervical dystonia (CD) has a wide range of non-motor (neuropsychiatric, sensory, dyssomnic) disorders. Relationships between dystonia, nonmotor manifestations the disease and patients quality life (QoL) require clarification. Objective: to clarify impact affective, behavioral disorders, sleep wakefulness on with CD. Patients methods. We examined 61 CD (mean age – 48.03±11.49 years, mean duration 4.89±4.05 years). used Toronto Western Hospital Spasmodic Torticollis Rating Scale (TWSTRS),...
Non-motor disturbances represented by sensory, affective, obsessive-compulsive disorders, cognitive dysfunction, sleep are often found in patients with dystonia and have a negative impact on their quality of life. The prevalence sensory affective disorders is above 50% cervical 25% blepharospasm, writing spasm; dysfunction more than focal dystonia. relationship non-motor, particular psychiatric the impairment social everyday life worsening whole was shown. Common pathophysiological...
