A brief overview of the brain

Image
A brief overview of the brain      The human brain is a highly complex organ, made of countless neurons and fibers; white matter and gray matter; lobes and glands. These structural components give the brain its form, but the way they connect with each other gives the brain its function. Until recently, scientists could only really study one aspect (structure or function) of the brain at a time. But now, scientists from several disciplines have worked together to study brain structure and function simultaneously and offer a new atlas for studying the whole brain at once. A new study published in Scientific Reports combines the best of several disciplines: neuroscience, image processing, and network theory. Researchers evaluated the brains of healthy adults to analyze the brain’s structural components and their functional activities. Diffusion images provided information about structural connections and functional magnetic resonance images provided information about resti

HIV-AIDS

HIV-AIDS What is it? The HIV-AIDS pandemic, which began in the early 1980s, is one of the most devastating events in modern history in global health. About 35 million people have already died of AIDS; and despite a slow decline, the mortality rate of this disease is currently around one million people per year. The majority of deaths attributable to this disease occur in sub-Saharan Africa, where some 25 million people living with HIV were counted in 2015, and about two-thirds of new infections occur. The term "AIDS" is a common name derived from the acronym "AIDS", which means " acquired immunodeficiency syndrome "; this syndrome refers to the gradual destruction of the immune system by the human immunodeficiency virus (HIV). AIDS is almost universally fatal, but with appropriate treatment, people with HIV do not reach AIDS; some of them can even have a long and healthy life. Some rumors, stories, and assumptions that HIV does no

Prevention of Alzheimer

Image
The person must take preventive measures to avoid the disease, especially those with a family history of this disease. Prevention includes avoiding and replacing the wrong practices with health, including: Regular and daily exercise, as this will help maintain the activity of the brain and nerves naturally even after reaching a large age, and these sports: jogging, swimming. Energize the brain daily with some mental exercises, reading, writing, thinking, because this will help to renew brain cells and protect them from inactivity and damage. To get a healthy social life, the association of people helps to get busy, and the mind does not surrender to the negative thoughts and boredom that leads to its inactivity, and the mental illness which is a catalyst for Alzheimer's disease. Eat healthy food containing nutrients such as Omega 3, antioxidants, vitamins and minerals, healthy and natural fats, and must avoid foods harmful to the mind, which cause him to id

A brief overview of the immune system

Image
A brief overview of the immune system The immune system protects the body against disease or other potentially damaging foreign bodies. When functioning properly, the immune system identifies and attacks a variety of threats, including viruses, bacteria, and parasites, while distinguishing them from the body’s own healthy tissue. The Lymphatic system consists of bone marrow, spleen, thymus and lymph nodes.  Bone marrow produces white blood cells or leukocytes. The spleen is the largest lymphatic organ in the body contains white blood cells that fight infection or disease. The thymus is where T-cells mature. T-cells help destroy infected or cancerous cells. Lymph nodes produce and store cells that fight infection and disease. Lymphocytes and leukocytes are small white blood cells that play a large role in defending the body against disease. The two types of lymphocytes are B-cells , which make antibodies that attack bacteria and toxins, and T-cells, which help

Holistic Nutrition

Holistic Nutrition  Our bodies are amazing supercomputers that are absolutely capable of healing themselves. But, it is up to YOU to nourish your body to ensure proper functioning and repair of your cells and tissues. I don’t think we question things enough. Why do we accept a diagnosis from our doctors and go with their plan? They came into the room for the shortest amount of time possible, asked all the wrong questions, barely let us speak and proceeded to think that they know what the best plan of attack is. Bullshit. You are the mind, body, and soul. Only you know what is best. Only you are responsible for getting yourself there. There are individuals such as health coaches, that can guide you through your journey and offer genuine support, but it is still your journey and it is important for you to put faith into knowing what is best. A good place to start evaluating your wellness is your digestion. It all begins in the area of your body that would cover an enti

Avoid some of the Main Brain Damaging Habits

Image
Avoid some of the Main Brain Damaging Habits              In our daily lives we carry out a set of negative habits that affect our health and our minds in particular. Here are some habits that should be avoided. 1. No Breakfast – People who don’t eat breakfast have lower blood sugar levels. This can lead to an insufficient supply of nutrients to the brain (and to underperformance in terms of thinking, processing, retrieval and memory skills). 2. Overreacting – This can flood the brain with chemical which interferes with clear thinking, logical analysis and memory. 3. Smoking – This can cause a shrinkage in the brain, and possibly lead to Alzheimer’s disease. 4. High Sugar Consumption – Consuming too much sugar interferes with the absorption of proteins and nutrients. These are essential for healthy brain development. 5. Air Pollution – The brain is the largest oxygen consumer in our body. Inhaling polluted air decreases the supply of oxygen to the brain. Again
