Keep reading to learn more about some of the most common disorders and diseases of the brain, and if you’re interested in learning more, consider pursuing a clinical psychology degree.

Brain Cancer

Brain cancer is a type of cancer that starts in the brain. There are many different types of brain tumors, but all start from cells in the brain. Brain tumors can be cancerous (malignant) or non-cancerous (benign). Brain cancer is a relatively rare type of cancer, accounting for less than 2% of all cancers. However, it is one of the most deadly types of cancer, with a five-year survival rate of only about 30%. The tumors can cause a wide variety of symptoms, depending on the size and location of the tumor. common symptoms include headaches, seizures, nausea and vomiting, changes in vision, and personality changes.

Symptoms can include confusion, difficulty speaking or understanding others, mood swings, problems with reasoning or judgment, and changes in personality. Dementia ranges in severity from mild to severe, and its symptoms can vary from day to day. There is no known cure for dementia, but treatments are available to help manage its symptoms. There is no one-size-fits-all approach to managing dementia symptoms. Treatment plans may include medications to improve cognitive function or treat specific underlying conditions; therapies such as occupational or physical therapy to help maintain independence and functioning; counseling for emotional support; and lifestyle changes such as diet and exercise modifications to improve overall health.


A stroke is a neurological emergency that occurs when blood flow to the brain is interrupted. This can be due to a blocked artery (ischemic stroke) or a ruptured blood vessel (hemorrhagic stroke). When the brain doesn’t get enough oxygen and nutrients, it can start to die. This can lead to disability or death. Symptoms of stroke include sudden numbness or weakness in the face, arm, or leg; trouble speaking or understanding speech; vision problems; dizziness; and headache. Stroke is treated with medications and/or surgery, depending on the cause.

Parkinson’s Disease

Parkinson’s disease is a chronic and progressive movement disorder that affects the nervous system. It is characterized by muscle rigidity, tremor, and slowed movements. Parkinson’s disease is the second most common neurodegenerative disorder after Alzheimer’s disease. The cause of Parkinson’s disease is unknown, but it is thought to involve both genetic and environmental factors. Most people with Parkinson’s disease are 50 years or older, but younger people can also develop the disease. There is no cure for Parkinson’s disease, but there are treatments available to help manage the symptoms. These include medications, surgery, and physical therapy.
