HIV does not attack brain cells. HIV (Human Immunodeficiency Virus) attacks cells in the body that fight infection and are involved with immune function. Confusion and memory loss could result from medications that are taken to treat HIV, or possibly infections resulting from the weakened immune systems of those infected with HIV.
Altitude sickness reduces the amount of oxygen in the brain, causing such symptoms as dizziness, shortness of breath, and mental confusion
It can cause confusion in the short term. But it would not cause long term memory loss, unless there was some type of brain damage.
Of course, a hit to the head can crush and destroy the normal anatomy of the brain and destroy, gray material, white material, arteres, veins, etc
what causes amnesia? Amnesia is most commonly associated with either brain damage through injury or degeneration of brain cells in dementia. In both cases, brain cells are lost, and due to the complex network connecting cells within the human brain, they cannot be replaced. Most significant brain damage occurs when the brain is injured, such as in a car accident or as the result of a fall or blow. These traumas tend to cause a state of confusion, and some memory is often lost. Infections that affect the brain, such as herpes or encephalitis may also cause memory loss. Severe alcohol or drug abuse, and malnutrition, act to deprive the brain of nutrients causing the death of brain cells. This can also cause significant loss of memories. Memory loss may sometimes result from stroke, if it affects the area of the brain concerned with memory functions.
Destroy their brain.
In about one-third of patients, the infection spreads from the blood into the brain, causing brain abscesses. This complication can trigger a range of symptoms including severe headache, confusion, disorientation, dizziness, nausea and.
Memory is stored in the brain's grey matter.
1. Attacks the brain 2. Causes impaired memory, thinking and behaviour 3. It causes your brain cells to shrink or even disappear 4. The material "tangles" in the centre of the brain cells 5. But "plagues" the outside of brain cells 6. It causes disruptions of messages to be passed through the brain 7. Causing brain cells to eventually die (Memory loss) 8. Memory loss starts from more recent memories to long-term memories when worsened.
Symptoms of severe brain injury can vary greatly, depending on which part of the brain is damaged. Unconsciousness can occur immediately after suffering trauma. Other possible symptoms include headache, loss of coordination, dizziness, confusion, memory problems, and difficulty speaking.
destroy it.
Memory is stored in the hippocampus region of the brain. We generally have two kinds of memory, short term and long term.
Drugs alter your brain chemistry and can even make you lose brain cells. They can make you lose your memory and destroy your health. Some drugs can be beneficial though, like chemotherapy drugs or medications for mental illnesses.
