What is Neuroscience?

Neuroscience is the study of how our brains and nervous systems work. It explores everything from how our brains are built to how they control our thoughts, feelings, and actions. Scientists in neuroscience use different tools and techniques to understand how brain cells communicate, how memories are formed, and why things go wrong in conditions like Alzheimer’s or depression.

By learning more about the brain, neuroscientists hope to find new ways to treat brain-related problems and improve our overall understanding of how we think and behave.

What are Neurodegenerative Diseases?

Neurodegenerative diseases are a group of conditions that primarily affect the neurons, which are the building blocks of the brain and nervous system. These diseases cause gradual damage or death to nerve cells over time, leading to progressive impairment in cognitive function, movement, and other neurological functions.

Examples of neurodegenerative diseases include Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, amyotrophic lateral sclerosis (ALS), and multiple sclerosis (MS). While the specific causes of these diseases vary, they often involve factors such as genetic mutations, abnormal protein accumulation, inflammation, and oxidative stress.

Neurodegenerative diseases can have profound impacts on a person’s quality of life and may eventually lead to severe disability or even death.
