The number of dementia cases is rising worldwide as more people live longer.

Each year, 10 million new cases of dementia are reported worldwide, with the number expected to hit 78 million in 2030.

However, there is still hope.

In August, The Straits Times reported that a study by the Institute of Mental Health (IMH) found that while the number of seniors with dementia rose from 51,934 in 2013 to 73,918 in 2023 - because of an increase in the adult population here the prevalence of dementia among older adults aged 60 and above here had dropped to 8.8 per cent, down from 10 per cent in 2013.

Additionally, the results of new research commissioned by medical journal The Lancet published in August found that up to 45 per cent of dementia cases could potentially be delayed or reduced.

Caused by damage to nerve cells and their connections in the brain, dementia is an umbrella term for various neurological conditions that lead to a decline in cognitive function, including Alzheimer's disease.

Though it is more common in those aged 65 and older, it can happen to anyone. There is no cure, though treatments are available to manage the symptoms and slow down its progression.

The third updated report of the Lancet Commission on Dementia identified two new risk factors that, if addressed, could prevent dementia.
