Memory Loss – Short Term Especially in Old Age
Q: Twice in the last two months my 70 years old friend could not remember what we talked on the phone at night. He had absolutely no memory of the phone conversation next morning. I am beginning to worry about this and would like to know if it might be serious. Thank you in advance for your answer.
It seem that he has a short-term memory loss called dementia. Fortunately, this memory loss is short-term and not long term. In long term memory losses, people forget their name, identity, where they live and almost everything. That condition is quite painful and difficult to manage.
Causes of Short Term Memory Loss
This type of memory loss is extremely common among people 70 years and above. It can be due to many reasons:
Just Old Age
As we age up, all faculties of our body become slow and start losing their performance. This is because of the wear and tear of cells and tissues over the years. Dementia (memory loss) would be seen here not just as a symptom but as a group of symptoms (syndrome). Other symptoms would include –
- Some loss of balance,
- Slurring of speech
- Loss of cognitive abilities
- Hard hearing
Fall or Injury to the Head Area
It is important to ask him if he had a fall or any other form of injury to the head area. Injury can leave its impact in the form of a blood clot or some hemorrhage in the brain. The accumulated blood can produce pressure on certain brain tissues giving specific symptoms like-
- Loss of memory
- Vision impairment
- Speech defect etc.
Onset of Alzheimer’s disease is another strong possibility. Here the patient is slightly disoriented. There is a clear loss of rational thinking. Loss of memory also accompanies. It is common at this age. If suspected, he needs to visit a doctor and start some medication.
Stroke or Multi-infarct Dementia
Till this age, the linings of the blood vessels become weak and thin. Blood vessels are friable now. Any increase in blood pressure or even otherwise, the blood may break and produce local hemorrhages in the brain tissue. This accumulated blood can also give symptoms like short term memory loss.
It usually runs in families. The patient typically has a mask-like face (lack of facial expressions). Gait is short stepped. Some tremors are also there, especially in the hands.
Inadequate amount of vitamin B12 in diet can also impair memory. Diet insufficient in dairy supplement can lead to such deficiencies. He should have at least 2 glasses of fresh cow milk daily at this age.
To make a diagnosis, you will have to observe him closely or ask him questions to see if any of the above conditions match with his. Only then we can intervene and start specific medicines.
