Neurodegenerative Diseases
Neurodegenerative diseases are disorders characterized by the progressive loss of structure or function of neurons, often leading to their death. These diseases are studied under the Department of Neuroscience, which focuses on understanding the structure and function of the nervous system and brain. Examples of neurodegenerative diseases include Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis (ALS), and multiple sclerosis (MS).

Explanation
Neurodegenerative diseases primarily affect the brain and spinal cord, impairing essential bodily functions like movement, memory, and cognitive processing. These disorders are usually associated with the accumulation of toxic proteins, inflammation, or genetic mutations. Some key processes involved include:
Neurodegenerative diseases primarily affect the brain and spinal cord, impairing essential bodily functions like movement, memory, and cognitive processing. These disorders are usually associated with the accumulation of toxic proteins, inflammation, or genetic mutations. Some key processes involved include:
- Protein misfolding: Abnormal protein aggregates (e.g., amyloid-beta in Alzheimer's or alpha-synuclein in Parkinson's) damage neurons.
- Mitochondrial dysfunction: Impaired energy production affects neuronal survival.
- Oxidative stress: An imbalance between free radicals and antioxidants leads to cellular damage.
- Genetics and environment: Inherited mutations and environmental factors can trigger disease progression.
Usage in the Future
