The brain is the most important organ in the human body. It is the main control center of our body, which controls all the activities that take place in our body. It is also responsible for the memory, emotions, thoughts, speech and behavior of an individual. The brain is made up of cells called neurons. These neurons are connected to each other through nerve fibers. The brain has two sides. One side is the left side and the other side is the right side. Each side has a specific function. The left side of the brain controls the right side of the body and vice versa.
The brain functions by receiving signals from the senses, processing these signals and transmitting them to the other parts of the body. These signals can be visual, auditory, olfactory or tactile.
There are different types of diseases that affect the brain. They are known as brain disorders. Some of the common brain disorders include Alzheimer\\\’s disease, Parkinson\\\’s disease and dementia.
Alzheimer\\\’s disease is a chronic degenerative disorder of the brain. It affects the brain cells and their connections. This causes loss of memory, inability to perform daily tasks and personality changes. It is a progressive disease and eventually leads to death. Alzheimer\\\’s can be prevented by maintaining a healthy lifestyle.
Dementia is a term used to describe various disorders that affect the brain. It is a group of neurological disorders that cause impairment in cognitive ability, memory and behavior. There are many types of dementias. Some of them are Alzheimer\\\’s, Lewy body dementia, vascular dementia and frontotemporal dementia.
Epilepsy is a neurological disorder characterized by recurrent seizures. It is caused due to abnormal electrical activity in the brain. There are different types of epilepsy. The most common type is generalized epilepsy. Generalized epilepsy is characterized by multiple seizures throughout the day. The other types of epilepsy include partial epilepsy, absence epilepsy and juvenile myoclonic epilepsy.
Parkinson\\\’s disease is a movement disorder that occurs due to the death of dopamine producing cells in the brain. It is characterized by tremors, rigidity and bradykinesia. Other symptoms include stiffness of the neck, shuffling gait, stooped posture and difficulty in walking. Parkinson\\\’s can also occur due to damage to the basal ganglia. This condition is known as Parkinson\\\’s plus syndrome.
Stroke is a medical emergency that occurs when there is a sudden loss of blood supply to part of the brain. Strokes can be caused due to a clot in a cerebral artery, bleeding into the brain or rupture of an aneurysm. Symptoms of stroke include weakness or numbness on one side of the body, confusion, trouble speaking, trouble walking, dizziness, loss of balance, vision problems, severe headache and loss of consciousness.
