What would you do if you had brain disease? The brain is the most important part of the human body. Without it, you would not be able to think, and more importantly, you would be dead. Two serious brain diseases are brain tumors and Alzheimer’s disease. A brain tumor is a massive growth of abnormal cells in the brain. There are many types of brain tumors. Some may be benign, which is noncancerous, or they may be malignant, which is cancerous (Brain Tumor). Alzheimer's disease is an unstoppable brain disease that gradually damages one's memory and thinking. Eventually, the ability to do simple tasks everyday even becomes destroyed. For most people, Alzheimer's disease show after the age of 60. This is known as late onset AD. Early onset is rarer, but much more serious. Symptoms show before the age of 60. AD is the most common form of dementia for older people (About Alzheimer’s Disease). Millions of people come down with brain disease every year. Two of the most deadly are Alzheimer's and brain tumors. Finding ways to prevent and treat these diseases are not easy. In fact, my grandmother has a form of Alzheimer’s disease, which is one reason why I chose to research brain disease, and figure out the causes and treatments of these two diseases. Brain diseases such as Alzheimer's and brain tumors affect millions of people every year. There are many causes and symptoms of these diseases, such as having a history of these diseases. Prevention is not proven, but some drugs may help one person.

The brain is the control center of the body. This means getting a brain diseases is very dangerous not only for your brain, but for your whole body. A brain disease is a disorder that occurs in the brain, which can range from being mild, such as a mere headache, to extremely severe, such as Alzheimer's disease and brain tumors. The cerebrum (cortex) of the brain is associated with most of the higher brain functions such as thinking and acting. The cortex consists of four sections, called "lobes". The frontal lobe is connected to reasoning, planning, speech, movement, emotions, and problem solving. The parietal lobe is associated with balance, recognizing, and movement. The occipital lobe is associated with vision. The temporal lobe is connected to hearing, memory, and speech. The cortex is highly wrinkled, making the brain more convenient, as this increases the brain's surface area, giving it more room for neurons. The cerebrum is divided into two hemispheres- the left hemisphere, and the right hemisphere. The right hemisphere is associated with creativity, and the left one is linked with logic. A bundle of nerve fibers, known as the corpus callosum connects these "hemispheres" (Brain Structures and their Functions). The cerebellum, which is also known as the "little brain", is similar to the cerebrum, since it also has two hemispheres and a highly folded surface. This part of the brain is linked with movement and balance. The cerebellum is assumed to be older...
