What could you recommend to me to improve brain function?

You will find a lot of information on this subject in our articles. I send links: https://www.gdziepolek.pl/artykuly/jak-poprawic-pamiec-i-koncentracje https://www.gdziepolek.pl/kategorie/preparaty-na-pamiec-i-koncentracje Among the activities improving the condition of the brain, I can still suggest learning / learning new areas of knowledge, e.g. foreign languages, courses developing interests. Physical activity also promotes a good form of the nervous system. Any manual work that requires precision will additionally support concentration training (eg crocheting, knitting, etc.). In case of doubt, you can use a paid teleadvice from a psychologist available on our website in the e-visit tab: https://www.gdziepolek.pl/telekonsultacja/z-psychologiem
