Brain Disorders and Diseases

Welcome to the fourth tutorial of our 5-part series about the brain. In this tutorial, we will discuss common brain disorders and diseases, their causes, symptoms, and treatments, and the impact they have on brain function and behavior.

Common Brain Disorders

There are many types of brain disorders and diseases that affect millions of people worldwide. Some of the most common include:

• Alzheimer's disease
• Parkinson's disease
• Schizophrenia

Alzheimer's Disease

Alzheimer's disease is a progressive neurological disorder that affects memory and cognitive function. It is caused by the accumulation of abnormal proteins in the brain that damage and kill brain cells. Symptoms include:

• Behavior

These disorders can have a profound impact on quality of life.

Conclusion

Brain disorders and diseases are a significant public health concern. They affect millions of people worldwide and can have a profound impact on brain function and behavior. Understanding the causes, symptoms, and treatments of these disorders is crucial to improving diagnosis, treatment, and care. In the final tutorial of our series, we will discuss brain imaging techniques and their role in understanding the brain.
