The human brain is the master regulator in charge of receiving, interpreting, and responding to various sensory inputs from the environment. However, disturbances of this process have an effect on general brain health and can manifest as hyper-sensitivity, or hypo-sensitivity thereby impinging upon an individual's capacity to function optimally in daily life. The five senses: sight, smell, touch, taste and hearing. The “sensory diet” is not food but a program of structured ac

Our brain is considered a “protected” organ in the body since it is surrounded by an anatomical structure made of different cell types that controls what can go inside and what can exit. The structure is called “the blood brain barrier” and as the name suggests, it is a “barrier” that acts like a gatekeeper to the brain. Normally, it keeps harmful things out and hold “good” things in. It also controls how various chemical molecules (including compounds we need or even make ou

What is longevity? In a nutshell human longevity can be defined as the ability to live beyond the average one’s life expectancy. However, longevity should not be confused with “lifespan”, the number of years we live, it should be intended more like the “health span” since it refers to a longer than average life but with an emphasis on maintaining both physical and mental well-being. In recent years, longevity has become also a field of medicine and biology which focuses on st

Sarcopenia is a clinical condition that is often overlooked; consequently, it can easily lead to a cascade of events that seriously compromise the general health and independence of the affected individual. The word "sarcopenia" originally derives from the ancient Greek and is formed by the combination of two words: sarx (σάρξ), meaning "muscle" or "flesh," and penia (πενία), meaning "poverty" or "deficiency." Thus, when we speak of sarcopenia, we are referring to a condition

During a recent trip to the Greek island of Kos, the birthplace of Hippocrates, I rediscover some of the reasons why its most famous son is considered a giant not only for medicine, but for human civilization. Born around 460 BC, Hippocrates is typically considered the "father of modern medicine" because he was the first to separate medicine from religion. He transformed healing from superstition into a rational, evidence-based type of science. He was a revolutionary for his

Parkinson’s Disease (PD) is a chronic degenerative disease of the Central Nervous System that impairs primarily the motor skills and speech of the individual who is affected by. It belongs to a group of medical conditions generally called "movement disorders". From a clinical point of view, it is characterized by muscle rigidity, tremor at rest, a slowing of physical movement, and, in extreme cases, a loss of physical movement. Symptoms of PD have been known since ancient t

High protein diets are becoming among the most popular particularly among young-adult people. While some dietary plans promote the daily use of a supplement (like protein shakes for body builders or gym goers), others suggest simply a larger than usual portion of a protein-rich diet to be consumed regularly. The question is: is this good for our health?

Age is the best-known risk factor for developing Alzheimer's disease. Besides age, another strong risk factor is a gene (a piece of DNA) called apolipoprotein E (APOE), which can exist as E2, E3 or E4. Of the three variants, only APOE4 increases the risk of Alzheimer’s significantly. Having APOE4 gene means you need to be proactive about prevention and follow healthy lifestyle (exercise, diet, socialize) to riduce the negative impact of APOE4 on brain health.

Lewy Body Dementia is an overlooked and often misunderstood clinical condition.
