Symptoms of Alzheimer’s Disease

Early Symptoms

The earliest symptom of Alzheimer’s disease is usually short term memory loss. People living with Alzheimer’s disease will typically forget what they did recently but may remember events from years ago in great detail. This can make people think that there can’t be anything wrong with their memory if they can recall information from so long ago. However it is this loss of short term memory that usually occurs early and which is so characteristic of the onset of Alzheimer’s disease.

The Difference Between Early Alzheimer’s Disease and Forgetfulness

We all forget things from time to time and this forgetfulness tends to increase with age. It can be difficult to judge whether this forgetfulness is a part of normal ageing. Typically it is the ‘depth’ of the memory loss that differs in ‘normal forgetfulness’ versus that due to Alzheimer’s disease.

A person with ‘normal forgetfulness’ can usually still remember other facts associated with the thing they have forgotten. For example, they may briefly forget their neighbour’s name but that the person they are talking to is their neighbour. A person with Alzheimer’s disease will often forget not only their neighbour’s name, but also the context in which they know them.

Stages of Alzheimer’s disease

Alzheimer’s disease is a complex condition that can affect people in different ways. There are, however, stages that many people will progress through and these reflect the movement of the disease through the brain. The symptoms that someone is experiencing will therefore often change, depending on the stage of their disease.

Early (or mild)

In the very early stages, day-to-day memory problems dominate but these can be subtle so it can be hard to tell if they are due to the normal ageing process.

Early warning signs to look out for include:

Losing or misplacing things
Becoming confused in familiar places
Taking longer to carry out everyday tasks
Changes in mood

Moderate

In this stage of Alzheimer’s disease, the problems with memory become more pronounced and other cognitive processes also start to become affected.

People may:

Tell the same stories or ask the same question repeatedly
Have difficulty recognising family members or friends
Have word-finding difficulties or non-fluent speech
Show a lack of concern over their appearance
Experience changes in mood and personality

Severe

In this stage, the disease spreads to engulf most parts of the brain and the person has what is termed ‘a global dementia’. All areas of cognition are severely affected but there are also problems with physical functioning.

People at this stage of disease may:

Be unable to remember their own name or recognise close family members
Suffer from bladder and bowel incontinence
Experience visual/auditory hallucinations
Develop repetitive or ritualistic behaviours
Need help with even the most basic activities of daily living

If you recognise signs of memory loss in a loved one that keeps on getting worse, to the point you are concerned about it, it is strongly recommended that you make an appointment to see a doctor for an assessment. The earlier that Alzheimer’s Disease is diagnosed, the more can be done to manage it.
