What is Memory Loss and What Causes It?

What Is Memory Loss?

As we age, it’s normal to forget things more easily. Memory loss can vary from forgetting something that happened just a few moments ago to more note-worthy events from a long time ago. There are many different types of memory loss. In addition, there are a wide variety of causes as to why this happens. It also differs from dementia in that a person with dementia is usually unaware of their loss of memory or could even deny it.

What Causes Memory Loss?

The most common causes  are anxiety, stress, and depression. Otherwise, it could be caused by a head injury, such as after a car accident. It could also happen after a stroke. This cuts off the blood supply to the brain and causes brain tissue to die. Other less common reasons for memory loss include an underactive thyroid or long-term alcohol misuse. Bleeding in the brain (i.e. a subarachnoid haemorrhage) is also another likely cause. Furthermore, it may also be due to a Vitamin B1 deficiency. Any problems with blood flow to the brain, a brain tumour, or a stressful or traumatic event also causes a person to block out the memory.
