The brain is the most critical part of the human body. It is the organ that controls and coordinates all the actions and reactions, allowing us to think and feel. The brain and its activities is collectively referred to as the nervous system. When it is working well, the nervous system will enable us to function efficiently on all levels. Our brain is the message centre, and functions are automatic. In the case of brain diseases, it can affect many things. The whole body system faces disruptions. Here, we shall learn how brain diseases impact our daily life, including memory, sensation, and our personality.
The three main representations of the brain are the cerebrum, cerebellum, and brain stem. Let us know more. Fig.2

Cerebrum – it covers a major part of the brain. It is composed of the right and left hemispheres. The cerebrum performs all higher functions such as interpreting vision, touch, and hearing. It is also responsible for speech, reasoning, emotions, learning, and the control of movements.
Cerebellum- it is located right under the cerebrum. The function of the cerebellum is to coordinate the muscle movements, maintain posture, and strike the right balance.
Brainstem- it acts as the relay centre. Its job is to connect the cerebrum and the cerebellum to the spinal cord. It performs automatic functions such as breathing, body temperature, waking, sleep cycles, digestion, sneezing, coughing, vomiting, heart rate, and swallowing.
Brain diseases can include conditions and disabilities that affect the brain. As mentioned earlier, the other name for brain activities is the nervous system. When our nervous system is working well, it allows us to function at all levels. We walk, talk, see and eat well. All this is possible due to the efficiency and working of our brain. Your brain is a control centre and an essential part of the nervous system. The system also includes the spinal cord and a vast network of neurons and nerves. (Fig.1).

When your brain is damaged, it can hurt many different things. Brian diseases include any condition or disability that affects your brain and its working. The disorders or diseases vary in the symptoms and severity. Brain diseases include conditions that are caused by the following factors:
1 – Genetic disposition or family history
2 – Any illness
3 – Traumatic injury
When a problem occurs with the nervous system, it can harm the whole body. Even the way you think, walk, talk, eat, and sleep gets affected. In some of the cases, neurological (brain) conditions can result in death. According to studies, brain and neurological disorders affect one in every six people. The brain and the nervous system is a complex structure. Any problem here and many things can go wrong.
1 – Traumatic brain injury including concussion, can be mild or severe. It can cause mild headaches to confusion, loss of consciousness, convulsions, and death. Injury to the spinal cord, such as a broken vertebral column which is a result of an automobile crash or any other accident can alter your life. This condition can lead to significant loss of neurological function. For instance, a person who has suffered spinal cord injury can become partially or fully paralysed. Symptoms include sleep disorders, loss of balance, speech problems, bleeding from the ear, visual problems, confusion, and disorientation. Treatment involves medication, neurocritical care, and immediate brain surgery to remove damaged tissue.
2 –Tumours – brain tumours or any growth can be benign (non-cancerous) or malignant (cancerous). Tumours can put pressure on brain tissue or destroy the brain tissue. It can lead to problems in the body organs that are associated with the area of the brain affected. Tumours can start from within the brain or metastasise (travel, spread) to the brain from other organs. Common brain tumours are Cancer, Glioblastoma, Astrocytoma, and Meningioma. Symptoms include headache, mood swings, dizziness, numbness, vomiting, paralysis, seizures, fatigue, and blurring vision. Treatment includes surgery, chemotherapy, radiation therapy, and rehabilitation.
3 – Neurodegenerative diseases can cause your brain and nerves to deteriorate. These conditions can change your personality and create confusion. One can also see the destruction of the brain tissue and nerves. Such brain diseases are genetic or develop as you age and slowly impair your memory and ability to think. The symptoms include forgetfulness, apathy, and memory loss, loss of inhibition, mood change, and anxiety. There is no cure but the treatment involves medications, exercises, and lifestyle changes to control symptoms.
1. What Is A Neurodegenerative Disease?
Neurodegenerative diseases can lead your brain and nerves to deteriorate. These conditions can change your personality and create confusion. One can also see the destruction of the brain tissue and nerves. Brain diseases such as Alzheimer’s develop as you age and slowly impair your memory and ability to think. Some conditions are genetic and begin in childhood. Alzheimer’s, Parkinson’s and all forms of Dementia are neurodegenerative diseases. Some of the common symptoms of neurodegenerative diseases include- forgetfulness, apathy, and loss of inhibition, mood change, and anxiety. Symptoms get worse with time, and new symptoms develop. There is no cure, but treatment can help with relief in symptoms.
2. Is There A Treatment For Neurodegenerative Brain Diseases?
Ongoing studies have shown potential in the relationship between proteins and mental disorders such as schizophrenia, depression, and autism. Still, there is lots of work to be done before the world can get concrete results. Brain diseases are incurable and result in progressive degeneration and death of neuron cells. There is no cure, but treatment and therapies can help. Treatment for Neurodegenerative brain diseases involves the use of medications to control the symptoms and maintain quality of life with lifestyle changes. The two major treatments are psychotherapy and medication. Different methods work in combinations to alleviate the problem.
