Factors that change your brain

The brain is made up of neurons, it acts as the command center of the entire nervous system of the body through receiving signals from organs, processing and sending information to other organs. target organ. The brain, spinal cord, and nerves form the central nervous system, involved in regulating the physical and mental functions of the body. Once the brain is damaged, the entire operating system is impeded. Here are the factors that cause the brain to change in both positive and negative ways.

When you experience something traumatic, your brain activates the "fight or flight" response. Most people recover on their own, but others develop post-traumatic stress disorder. Post-traumatic stress disorder causes the amygdala, the part of the brain that controls emotions, to become overactive, and it reduces activity in the prefrontal cortex, a decision-making area. It can also shrink the hippocampus, where memories form.

Depression doesn't just affect your mood, it can change your brain. Experts say it reduces activity in several brain regions, including the prefrontal lobe, which is involved in things like reasoning, personality and judgment. One study found that people who had been depressed for more than a decade had about 30% more encephalitis. This can lead to brain cell loss, making memory problems and dementia more likely.

A stroke occurs when blood flow to part of the brain is stopped. They cause permanent brain damage, which can lead to death and disability. Symptoms will depend on where the stroke occurred. If it is on the left side of the brain, you may experience weakness and numbness in the right side of your body and talking may also be difficult. If the stroke is on the right side, you may experience weakness or numbness on the left side.

It's no secret that alcohol affects the brain. It can cause blurred vision, slurred speech, and memory loss. That's because alcohol kills brain cells. Over time, drinking too much can damage the brain, or it can also shrink certain parts of the brain. Some experts say that alcoholics have smaller hippocampus, an area important for learning and memory, than people who don't drink regularly.

People with schizophrenia have different brains than people without this mental disorder. Scans showed that people with schizophrenia lost gray and white matter, the fat that makes up the brain. White matter is located deep in the brain, where information travels. Gray matter surrounds it and, among other things, helps the brain process information. In people with schizophrenia, gray matter tends to leave first, and white matter fades over time.

The brain has cells called neurons. They communicate with each other through chemical and electrical signals and send messages to the rest of the body. Alzheimer's disease disrupts this communication. It is thought that the breakdown comes from the accumulation of two proteins, amyloid and tau. Both create confusion that can disrupt communication.

People with migraines have faulty wiring in the brain. Certain nerves overreact to triggers, such as stress or bright light. This creates a wave of activity, which causes chemicals to narrow blood vessels in the brain. That leads to headaches and other symptoms. Over time, chronic migraines can cause you to lose some gray and white matter.

A brain aneurysm is a weak spot in a blood vessel. It usually bubbles or swells and fills with blood, looking like a berry hanging from a tree branch. They usually form on the arteries at the base of the brain. Some aneurysms leak or rupture. That causes bleeding in your brain or the area between your brain and its lining. These are hemorrhagic strokes. They can start as headaches but can lead to nausea, seizures, and death.

Any risk, such as a car crash or head impact, can cause a concussion. During the collision, the brain slides and collides with the inside of the skull. This can bruise the brain and tear nerve tissue. Concussions also disturb the balance of chemicals in the brain, damaging nerve cell function and causing inflammation. Although the brain usually heals on its own, repeated concussions can lead to long-term damage.

Scientists are still looking into which brain changes cause the intense mood swings of bipolar disorder. They think they are the result of an imbalance of neurotransmitters. These chemicals send messages between brain cells. They play a role in things like mood, sleep, and memory. For example, too much of a neurotransmitter called noradrenaline can cause mania, while too little sets the stage for depression.

With multiple sclerosis, the immune system attacks the nerves in the brain and spinal cord. The body sends white blood cells to damage myelin, the insulation around nerves. This causes nerve damage and disrupts the flow of information to and from the brain. Over time, scar tissue forms on the nerve and creates lesions. These changes lead to things like numbness, tremors, and vision problems.

Experts believe that symptoms of ADHD in adults, such as inattention and hyperactivity, stem from brain differences. Research shows that there is less gray and white matter in adults with ADHD. Some areas also take longer to form. Furthermore, the network of neurons behaves differently. These networks send signals in the brain and they play a role in attention and concentration.

This mind-body practice reduces stress and boosts mental health. Now, research reveals that it can actually change your brain. One study found that meditating for 2 months increased gray matter in the parts of the brain that control emotions and learning. Meditation also strengthens connections between brain cells. It may also calm inflammation in the brain and protect against Alzheimer's disease.

Exercise is good for the body and brain. Exercise can help with blood flow to the brain, which provides oxygen and nutrients. It also stimulates the release of proteins that keep brain cells healthy and help grow new cells, aiding in the development of brain regions that control your thinking and memory.
