Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Alzheimer's disease is the most common disease responsible for dementia, accounting for 40-70% of all dementia cases. Alzheimer's disease is characterized by a gradual and slow decline in memory and other cognitive functions and activities.

The medications currently used in Alzheimer's disease were introduced in the 1990s and exhibit insufficient effectiveness. Despite their use, the disease rapidly progresses, leading to complete loss of independence and death. There are conducted numerous studies on new molecules, however none of them has been successfully accomplished so far. Transcranial magnetic stimulation (TMS) is one of the youngest electrophysiological methods, enabling non-invasive and painless stimulation of the central and peripheral nervous system. Another non-invasible neurophysiological method that is utilized in treating patients with neurological dysfunctions and mental disorders is Transcranial direct current stimulation (tDCS). Clinical trials conducted with isolated usage of rTMS and tDCS showed a positive effect of these methods on the enhancement of cognitive functions in patients with Alzheimer's disease.

The aim of the project is to evaluate the effectiveness and safety of the combination of Repetitive Transcranial Magnetic Resonance (rTMS) with Transcranial direct current stimulation in the treatment of Alzheimer's dementia. The primary goal of the project is to assess whether the use of combined tDCS and rTMS therapies in patients diagnosed with mild to moderate Alzheimer's disease improves patients' cognitive functions, including memory, attention, thinking, executive and language functions. The research hypothesis assumes that the combination of rTMS and tDCS therapy is an effective method of Alzheimer's disease therapy that can improve cognitive functions and functioning of patients, both in the short and long term.
