Neurotechnology is a rapidly developing field that aims to better understand the brain and nervous system, optimize cognitive functions and treat age-related neurological diseases. As the population ages, diseases such as Alzheimer's, Parkinson's and other neurodegenerative disorders are increasingly becoming the focus of research. Technologies such as brain-computer interfaces (BCIs) and brain implants offer new possibilities to treat these diseases by directly supporting or improving neuronal communication.

• BCIs enable direct interaction between the brain and external devices. They work by converting brain signals into digital information that can then be used to control computers, prostheses or even communication systems. For people suffering from neurodegenerative diseases, BCIs could help to restore lost motor functions, support cognitive abilities or improve memory. For example, deep brain stimulation (DBS) technologies are already being used in the treatment of Parkinson's patients to regulate uncontrolled movements. This type of neurotechnology is a precursor to even more advanced BCIs, which could not only alleviate symptoms but also address the underlying cognitive deficits in old age.
• In the long term, brain implants could not only be used to treat neurological diseases, but also to improve cognitive abilities in old age. Brain implants can amplify neuronal signals and thus possibly slow down or even stop memory loss in Alzheimer's disease. Studies have shown that certain regions of the brain can be reactivated by implants, leading to improved cognitive function.
• Future visions of neurotechnology include the idea of cognitive enhancement, where implants or BCIs could not only correct disease conditions but improve the brain beyond its natural limits. This would allow older people to maintain high levels of cognitive function as they age, not only improving their quality of life but also enabling them to remain active in the labor market and in society for longer.
• By combining neurotechnology with other areas of longevity research such as artificial intelligence (AI) and genetics, neurotechnology could be a key to extending lifespan by protecting the brain while expanding its potential.
