The purpose of the investigation was to study the nootropic effects of rhythmic transcranial magnetic stimulation (rTMS) using low-intensity magnetic field with the induction rate of 45 mT, base frequency of 50 Hz, modulation frequency of 10 Hz in combination with standard medical and psychological therapy in the rehabilitation of patients with post-stroke cognitive impairment (PSCI). Materials and methods. The rehabilitation outcomes in 98 patients with PSCI syndrome were studied. The patients were subdivided into 2 groups: 53 patients of the control group were treated with the standard nootropic medications and neuropsychological procedures; 45 patients of the main group were additionally treated with rTMS by the low-intensive running pulsed magnetic field of 10 Hz modulation frequency. The dynamics of the score increase according to Rivermid, Karnovsky, Roshina, MMSE, mRS, HDRS, SF-36 scales were analyzed. Conclusion. Application of rTMS with low-intensive running pulsed magnetic field of 10 Hz modulation frequency in combination with a standard program of cognitive rehabilitation contributes to a significant improvement in the recovery of mental calculation function in ischemic stroke patients, as well as normalization in mood swings in the patients who had suffered a hemorrhagic stroke and post-stroke depression. This variant of rTMS can be safely used in patients with PSCI syndrome in the early recovery period, 3 weeks after the onset of stroke.

The Brain

Electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS) and deep brain stimulation (DBS) all entail the delivery of electrical impulses to the brain with the aim of relieving mental disorders. ECT is an effective treatment of depression, mania and catatonia and, to a lesser extent, of schizophrenia. Its side effects, principally cognitive impairment, are mitigated through the use of individually tailored, unilateral delivery. TMS is more convenient but of lesser effectiveness. DBS, while reversible and thus safer than lesional surgery, is a major undertaking that is reserved at present for profoundly disabling depression, obsessive-compulsive disorder (OCD), and Tourette’s syndrome.

Disease Modifying Drugs

The exact relationship between cognitive functioning, cortical excitability, and synaptic plasticity in dementia is not completely understood. Vascular cognitive impairment (VCI) is deemed to be the most common cognitive disorder in the elderly since it encompasses any degree of vascular-based cognitive decline. In different cognitive disorders, including VCI, transcranial magnetic stimulation (TMS) can be exploited as a noninvasive tool able to evaluate in vivo the cortical excitability, the propension to undergo neural plastic phenomena, and the underlying transmission pathways. Overall, TMS in VCI revealed enhanced cortical excitability and synaptic plasticity that seem to correlate with the disease process and progression. In some patients, such plasticity may be considered as an adaptive response to disease progression, thus allowing the preservation of motor programming and execution. Recent findings also point out the possibility to employ TMS to predict cognitive deterioration in the so-called “brains at risk” for dementia, which may be those patients who benefit more of disease-modifying drugs and rehabilitative or neuromodulatory approaches, such as those based on repetitive TMS (rTMS). Finally, TMS can be exploited to select the responders to specific drugs in the attempt to maximize the response and to restore maladaptive plasticity. While no single TMS index owns enough specificity, a panel of TMS-derived measures can support VCI diagnosis and identify early markers of progression into dementia. This work reviews all TMS and rTMS studies on VCI. The aim is to evaluate how cortical excitability, plasticity, and connectivity interact in the pathophysiology of the impairment and to provide a translational perspective towards novel treatments of these patients. Current pitfalls and limitations of both studies and techniques are also discussed, together with possible solutions and future research agenda.
