Our findings suggest possible association of migraine with aura and PFO. It seems that PFO does not influence the type of aura and frequency of attacks of migraine as well as it is not associated with familial occurrence of migraine.

A number of evidence revealed a link between temporal information processing (TIP) and language. Both literature data and results of our studies indicated an overlapping of deficient TIP and disordered language, pointing to the existence of an association between these two functions. On this background the new approach is to apply such knowledge in therapy of patients suffering from language disorders. In two studies we asked the following questions: (1) can the temporal training reduce language deficits in aphasic patients (Study 1) or in children with specific language impairment (SLI, Study 2)? (2) can such training ameliorate also the other cognitive functions? Each of these studies employed pre-training assessment, training application, post-training and follow-up assessment. In Study 1 we tested 28 patients suffering from post-stroke aphasia. They were assigned either to the temporal training (Group A, n = 15) in milliseconds range, or to the non-temporal training (Group B, n = 13). Following the training we found only in Group A improved TIP, accompanied by a transfer of improvement to language and working memory functions. In Study 2 we tested 32 children aged from 5 to 8 years, affected by SLI who were classified into the temporal training (Group A, n = 17) or non-temporal training (Group B, n = 15). Group A underwent the multileveled audio-visual computer training Dr. Neuronowski®, recently developed in our laboratory. Group B performed the computer speech therapy exercises extended by playing computer games. Similarly as in Study 1, in Group A we found significant improvements of TIP, auditory comprehension and working memory. These results indicated benefits of temporal training for amelioration of language and other cognitive functions in both aphasic patients and children with SLI. The novel powerful therapy tools provide evidence for future promising clinical applications.

Objective:Deep brain stimulation (DBS) was approved by Food and Drug Administration for Parkinson’s disease, essential tremor, primary generalised or segmental dystonia and obsessive-compulsive disorder (OCD) treatment. The exact mechanism of DBS remains unclear which causes side effects. The aim of this review was to assess variables causing stimulation-induced chronic psychiatric/personality-changing side effects.Methods:The analysis of scientific database (PubMed, Cochrane Library, EMBASE) was conducted. The included articles had to be research study or case report and DBS to be conducted in therapeutic purposes. The researches with mental disorders in patients’ medical histories were excluded.Results:Seventeen articles were used in the review. In the group of movement disorders the characteristic of side effects was strongly related to the placement of the electrode implantation. Tiredness/fatigue was correlated with DBS in thalamus. Implantations in subthalamic nucleus were mostly followed by affective side effects such as depression or suicide. The higher voltage of electrode was connected with more severe depression after implantation. The analysis of affective disorder contained only three articles – two about OCD and one about depression. Forgetfulness and word-finding problems as activities connected with cognition may be an inevitable side effect if obsessive thoughts are to be inhibited.Conclusion:DBS of subthalamic nucleus should be seen as the most hazardous place of implantation. As a result there is a strong need of ‘gold standards’ based on the connectivity research and closer cooperation of scientists and clinicians.

It is known that mutations of CACNA1A, which encodes a neuronal P/Q Ca(2+) channel, are present in patients with familial hemiplegic migraine, and possibly in other types of migraine as well. This calcium channel is also involved in neuromuscular transmission. To assess if the single-fibre EMG (SFEMG) method can demonstrate a neuromuscular transmission deficit in migraine, a group of 26 patients with different types of migraine and 20 healthy control subjects were studied. The migraine patients were divided into three groups: 8 patients with migraine without aura (MoA), 12 with migraine with aura excluding visual aura (MA) and 6 with visual aura (VA). A SFEMG of the voluntarily activated extensor digitorum communis muscle was performed. The SFEMG results were normal in the healthy controls and the MoA group (migraine without aura). Slight neuromuscular transmission disturbances were present in 6/12 (50%) of patients with MA and in 1/6 (17%) of patients with VA. We suggest that abnormal neuromuscular transmission detectable by SFEMG may reflect a genetically determined dysfunction of the P/Q Ca(2+) channels in a subgroup of migraineurs with aura.

The COVID-19 pandemic causes increased mental stress and decreased mobility, which may affect people with Parkinson’s disease (PD). The study aimed to investigate the secondary impact of the COVID-19 pandemic on the level of activity, quality of life (QoL) and PD-related symptoms. The respondents completed an online survey in Polish in the period from December, 2020 to June, 2021. The questionnaire was completed by 47 participants aged 43 to 90 years (mean 72.1 ± 1.3 years). A total of 94% reported reduced contact with family and friends. Over 90% remained active during the pandemic. However, 55% of people with PD showed subjectively lower level of activity then before the pandemic. Moreover, 36% of the respondents felt afraid to visit a doctor and reported problems with access to medication. Subjective QoL reduction was reported by 80%, and 83% declared worsening of PD symptoms. The post pandemic deterioration of motor symptoms in people with PD did not affect their QoL. However, the deterioration of contacts and feelings of isolation had a significant impact on the decline in quality of life (p = 0.022 and p = 0.009, respectively) and the presence of anxiety (p = 0.035 and p = 0.007, respectively). These results may indicate than greater importance of social and mental factors than fitness and health-related factors in the QoL self-assessment of the people with PD.
