Memory loss (amnesia) is an inevitable part of the aging process. As we grow older it becomes more noticeable that we forget people’s names or where we have put our bags, as well as appointments and events. Most of these memory lapses are just a normal part of the aging process, but sometimes they can be an indication of a developing memory problem. It is important to recognize the symptoms for memory related illnesses, and understand how they can treated. Many instances of cognitive memory loss which have an organic cause can be treated, if detected and recognized early, helping the patient lead a fuller life.
The brain has over 100 billion nerve cells called neurons, and these cells carry all the information and memories to and from the brain and the rest of the body in split seconds. When neurons have to communicate or pass on information, they do so using the connections in the brain called synapses. Over time, the synapses within the brain begin to weaken which affects how easily and quickly it is to retrieve memories. Another cause of memory loss occurs when the white matter which links different parts of the brain begins to die off, as the blood supply to the brain has diminished, again usually due to old age. Forgetfulness also occurs when the memory is not exercised enough to retrieve information to reconsolidate memories, which is why brain training exercises form a large part of treatment.
Some common triggers for identifying a memory loss problem include:
Normal age related forgetfulness
This is common as you age and includes things like forgetting your glasses, difficulty recalling names or walking into a room and forgetting why you entered. You are normally able to recall and describe episodes of forgetfulness after they occur.
Memory loss can also result due to stress. If you are stressed or very anxious your body releases more of a hormone known as cortisol. It has been shown that excess cortisol can increase memory loss. Anxiety is an intense distraction and as you are distracted you have problems with your memory as your focus is elsewhere. Sleep deprivation also contributes to anxiety and therefore influences your memory.
Memory loss should always be investigated, as sometimes it may be caused by underlying conditions or trauma. Some examples of these are: stroke; head injury; underactive thyroid (hypothyroidism); certain medications you may be taking; vitamin B1 (thiamine) deficiency; and subarachnoid haemorrhage.
Mild cognitive impairment (MCI) and dementia
This is an intermediate stage between normal age related conditions and more serious dementia. Mild cognitive impairment normally progresses to more serious forms of dementia such as Alzheimer’s disease, but if recognized and treated early with medications then the deterioration can be slower and managed more effectively. Symptoms of MCI and dementia include difficulty performing normal day to day activities including paying bills, dressing or doing household chores, unable to recall instances of memory loss, getting lost or disorientated, forgetting words, sentences or repeating phrases, and trouble making choices or decisions.
Identifying the types of memory loss you are experiencing is very important. Types of memory loss include:
If you are experiencing some memory loss or you want to prevent symptoms occurring, there are certain things you can do to help keep your neurons and synapses firing, and help pick up on any more serious memory problems quickly.
