In a study sponsored by National Credit Systems, it was found that a lack of vitamin B12 can lead to reduced memory diseases. Approximately 40% of women become more scatter-brained in menopause. Memory can be affected after a flight lasting more than four hours.
1. High blood pressure
The studies that are carried out on more than 30 thousand people in America for four years show that people with high blood pressure remember worse in the tests of memory and their memories are reduced faster over time.
An expert from Baker IDI Heart and Diabetes Institute said: “The increase in blood pressure could mean a change in the structure of blood vessels making vessel walls thicker and the blood flow in the body becomes difficult. As a result, the organs in the body can also be damaged. The brain is one of them. This affects the perception and mind of the human. So, maintain a balanced diet, proper weight, exercise regularly, do not smoke. If you are taking blood pressure medication, you should drink drugs regularly to stabilize blood pressure.
2. Long flights
Memory can start to be affected after a flight lasts more than four hours. This causes headaches and may affect short-term memory. Normally, people will recover but can’t remember exactly what happened at that time.

3. Lack of vitamin B12
According to a spokesman of Dietitians Association of Australia, lack of vitamin B12 can lead to the changes in perception, from amnesia to reduced memory disease. Scientists believe that vitamin B12 may protect the myelin sheath – the shell surrounds the axons of neurons. If this shell is damaged, it can affect the transmission messages to the brain and from the brain to elsewhere.
4. Menopause
People who conducted the research of the University of Illinois in 2008 found a link between the attacks of “hot flashes” and poor memory in women during menopause. This study shows that about 40% of women become more scatterbrained in menopause.
The more attacks of “hot flashes” women have, the poorer memory they have. Maki also found that women with hot flashes are often disrupted in sleep and have worse memory.

A doctor from Women’s Health says that although there is no clear evidence to suggest that menopause causes dementia, many women in this period continue to feel messing before everything. She said: “People often have to ‘fight’ for finding words and forget others names. Women should talk with their doctor about these symptoms if it affects their lives.”
5. Chemotherapy
The study of Stanford University (USA) shows that breast cancer patients undergoing chemotherapy suffer some impacts on the parts of brain that are responsible for memory.
According to the CEO of Australia Cancer Institute, one of the unwanted side effects of chemotherapy is “chemo brain” (chemotherapy makes the function of the brain reduce). This effect may be slight or significant, depending on the circumstances. It is the mild amnesia that occurs in a short period of time when conducting therapy and most cases are back to normal then.
6. Thyroid problems
Hypothyroidism is the condition of reduced thyroid function leading to decreased production of thyroid hormones. Since then, it slows the metabolism, causes fatigue and can make memory reduced. Hypothyroidism usually occurs after the age of 40 and affects about 6 to 10% of women and a smaller number of men.
A spokesman of the Royal Australian College of General Practitioners says that when you have a health problem causing fatigue, you will easily become more scatterbrained. But when hypothyroidism is treated, people will recover and their memories are also recovered. Hypothyroidism can be treated with drugs.
7. Alcohol
Drinking too much alcohol can cause negative effects on the hippocampus – the part of the brain having the functions of storing information and memory formation. It prevents the transfer of memory from short-term memory into long-term one. So, the drinkers can’t often remember what happened during their drinking time.
8. Pregnancy
Pregnancy can affect women’s memory. According to a member of a research of the University of New South Wales: “The jobs that require the frequent remembering like remembering the phone numbers of friends are often difficult to be affected . However, that’s another thing when you have to remember the new numbers or keep in mind other information series “. She says the sudden changes of the body during pregnancy may be the cause.
