Common features include:
As the condition progresses, some people may develop difficulty expressing themselves, reduced understanding and weaker judgement.
In more advanced stages, daily planning and independent self-care may also be affected. When cognitive changes become more frequent and begin to affect day-to-day function, clinical assessment is needed to determine whether this is dementia rather than simple age-related memory decline.
Dementia is a group of neurodegenerative conditions characterised by ongoing decline in cognitive function. Common types include:
This is the most common type and is associated with abnormal protein build-up in the brain and progressive nerve degeneration.
This is related to cerebrovascular disease or a history of stroke.
These are less common, but each has its own characteristic clinical features.
The main areas commonly affected include:
Disease characteristics:
Current treatment focuses on slowing decline and maintaining function.
This may include cholinesterase inhibitors, NMDA receptor modulators and other appropriate medicines.
These approaches aim to support memory and thinking function.
These help reduce confusion and lower safety risks.
Management of blood pressure, blood glucose and cholesterol may help reduce vascular contribution to cognitive decline.
Clinical focus: early recognition and ongoing management may help slow functional decline.
In Chinese Medicine, dementia is often discussed within the categories of forgetfulness and cognitive decline. It is generally understood as a mixed pattern of deficiency and excess, with deficiency as the main underlying basis.
From the perspective of disease progression, the early stage is often related to Kidney essence deficiency. In Chinese Medicine, the brain is regarded as the sea of marrow, and when essence is depleted, the brain is less well nourished, leading to decline in memory and responsiveness.
As the condition develops, Qi and Blood deficiency may further reduce nourishment, resulting in slower thinking and reduced mental vitality. At the same time, phlegm turbidity and blood stasis may obstruct the clear orifices, affecting thinking, judgement and verbal expression.
Common underlying patterns include:
This may be associated with reduced memory and slower responsiveness.
Reduced support for mental clarity and vitality may contribute to slower thinking and reduced alertness.
This may present as dull responses, reduced clarity and difficulty with expression.
Impaired circulation may be associated with gradual decline in cognitive function.
Overall, this condition may be understood as Kidney essence and Qi-Blood deficiency as the root, with phlegm and blood stasis obstructing the clear orifices as the branch.
Assessment considers cognitive changes, behavioural presentation and overall constitution to identify the main clinical pattern.
Common Chinese Medicine patterns include:
The core of pattern assessment is to determine whether deficiency is the main issue, or whether obstruction is having a greater impact on cognition.
For dementia, the treatment focus is strengthening underlying support, helping open and clear the orifices, and maintaining function, alongside neurological care.
Treatment focuses may include:
Helping support memory and thinking function.
Supporting clearer mental function and better cognitive processing.
This may include support for sleep, mood and daily rhythm.
The aim is to help maintain day-to-day ability and quality of life.
Depending on the individual situation, treatment may include Chinese herbal medicine, acupuncture and lifestyle advice. This should be coordinated with neurological assessment and medical treatment.
If dementia has already been diagnosed, or the person is in an early observation stage, Chinese Medicine support may be considered when the following concerns are present:
Clinical focus: whether the person has entered a stage that requires long-term cognitive and functional support.
However, specialist assessment should be prioritised if any of the following occur:
Dementia is a chronic progressive condition. Alongside appropriate medical care, longer-term adjustment and functional support may help maintain cognition and quality of life.
