Emerging Research and Innovations in Dementia Care
Dementia is a medical condition that affects cognitive abilities, such as memory, language, and decision-making skills. Dementia can result in brain damage and is frequently associated with conditions such as Alzheimer's or Parkinson's disease.
The following are crucial things to know about dementia:
- Dementia is not a normal part of ageing. It is a medical condition that requires diagnosis and treatment.
- Dementia is a group of degenerative mental diseases that cause cognitive function loss beyond normal ageing.
- Alzheimer's is the most common type of dementia.
- Plaque deposition in the neurons causes Alzheimer's, leading to a loss of brain function and neuronal death.
- Dementia can impact daily life, including the ability to perform everyday tasks like cooking and dressing.
- There is currently no cure for dementia, but there are treatments and strategies that can help manage the symptoms and improve the quality of life.
- The exact cause of dementia is still unclear, but research links it to genetic susceptibility and mental age.
- Dementia affects around 50% of people aged 85 and older, according to estimates.
- Medications available today may help slow down the mental decline associated with dementia.

What is the difference between dementia and Alzheimer’s disease?
- Dementia is a group of degenerative mental diseases that cause deliberate cognitive function loss beyond normal ageing.
- Dementia is an umbrella term for a group of mental diseases that cause cognitive impairment, while Alzheimer's is a specific disease that causes cognitive impairment and memory loss.
- Other types of dementia include Lewy body dementia, Parkinson's disease dementia, and vascular dementia, among others.
- Alzheimer's disease is the most common type of dementia, accounting for around 60–80% of cases.
Understanding the difference between dementia and Alzheimer's is vital for accurate diagnosis and effective treatment.
Are there different types of dementia?
Yes, there are different types of dementia. Dementia is not a single disease but a group of degenerative mental disorders that cause severe cognitive function loss beyond normal ageing. Some common types of dementia include:
- Alzheimer's disease is the most common type of dementia, accounting for around 60–80% of cases.
- Vascular dementia: A stroke or other conditions that block or reduce blood flow to the brain cause this type of dementia.
- Lewy body dementia: The accumulation of abnormal protein deposits in the brain causes this type of dementia, leading to hallucinations and movement problems.
- Frontotemporal dementia: Damage to the frontal and temporal lobes of the brain causes this type of dementia, which can result in changes in behaviour, personality, and language abilities.
- Parkinson's disease dementia: This type of dementia occurs in people with Parkinson's disease and causes a decline in cognitive function and memory loss.
- Mixed dementia is a type of dementia that involves a combination of two or more types of dementia. The most common mix is Alzheimer's disease with vascular dementia in people aged 80 and over. This type of dementia can be challenging to diagnose because symptoms may be more prominent than others, and there may be an overlap in symptoms between the different types. Additionally, people with mixed dementia experience a faster decline.
It is vital to note that there are many other types of dementia, each with its symptoms and causes. Understanding the type of dementia a person has is crucial for accurate diagnosis and treatment.
What are the symptoms of dementia?
- Common symptoms include confusion, forgetfulness, difficulty with language, mood swings, and a gradual loss of bodily functions.
- People with dementia may also experience changes in personality and behaviour, such as agitation, anxiety, depression, and withdrawal from social activities.
- In the early stages of dementia, people may have adversity in their short-term memory, such as forgetting recent conversations or events.
- As dementia progresses, individuals may experience long-term memory loss and difficulty with tasks that require concentration and reasoning.
- People with dementia may face challenges with everyday tasks, such as cooking, cleaning, and managing finances.
- In some cases, dementia can also cause hallucinations, delusions, and paranoia.
Symptoms of dementia can vary depending on the type of dementia and the severity of the disease.
What are the causes of dementia?
Dementia occurs when the brain is damaged and the affected nerve cells impair their ability to communicate with other parts.
- Many factors can block blood flow to the brain, deprive it of oxygen and nutrients, and cause damage that leads to dementia. This damage can cause brain tissue to die and result in the symptoms associated with dementia.
- A genetic mutation that affects the ability to function is the cause of Huntington's disease and dementia.
- Other factors that can contribute to the development of dementia include head injuries, infections, and nutritional deficiencies.
Medical professionals diagnose dementia through sequence assessments that test memory, problem-solving skills, language abilities, and other cognitive functions. These assessments include brain scans, blood tests, and other medical exams that help identify the underlying causes of the symptoms.

What medications are available to manage dementia?
- Cholinesterase inhibitors: These medications work by increasing the levels of acetylcholine in the brain, which helps improve cognitive function and slow the progression of dementia. Examples include donepezil, rivastigmine, and galantamine.
- Memantine: This medication regulates the levels of glutamate in the brain, which can help improve cognitive function and delay the onset of severe dementia symptoms.
- Antidepressants: Antidepressants can help alleviate depression and anxiety symptoms that often accompany dementia and improve sleep patterns.
- Antipsychotics: These medications can help manage behavioural symptoms such as aggression, agitation, and delusions in individuals with dementia. It is crucial to monitor the use of antipsychotics closely, as they can have side effects and are generally not recommended for long-term use.
- Anxiolytics: These medications can help manage anxiety symptoms in individuals with dementia but may also have side effects, and we need to use them cautiously.
What are the recent updates in dementia treatment?
- The FDA approved a new drug called Aduhelm (aducanumab), which is used to slow cognitive decline in patients with Alzheimer's disease by reducing the buildup of amyloid beta plaques in the brain. However, this drug is controversial.
- Research into non-pharmacological interventions, such as lifestyle changes (e.g., exercise, diet), cognitive stimulation therapy, and music therapy, has shown promise in improving function and quality of life for people with dementia.
- Studies investigating the use of technology, such as virtual reality and telemedicine, to enhance dementia care and support for patients and their carers.
Researchers are working hard to find new medications to combat dementia. They target different aspects of the disease, including inflammation, oxidative stress, and protein misfolding, to slow or stop its progression.
Routine changes in cognition can occur with age, but it is important to note that confusion and memory loss are not inherent to healthy ageing. We acknowledge age-associated memory impairment as a typical aspect of ageing, distinguishing it from dementia. Dementia, characterised by a decline in cognitive functions such as thinking, remembering, and learning, is not a natural component of the ageing process. It is vital to recognise that dementia signifies a significant deterioration in mental abilities beyond what is considered typical with age.
How can yoga and meditation help to prevent dementia?
Yoga and meditation can potentially help prevent dementia in a few different ways:
- Reducing stress: Chronic stress can lead to inflammation and oxidative stress, linked to an increased risk of cognitive decline and dementia. Yoga and meditation can help reduce stress levels, which may help protect the brain from damage.
- Improving brain function: Research has demonstrated that yoga and meditation can enhance cognitive function and improve brain connectivity, potentially protecting against age-related decline.
- Promoting healthy blood flow to the brain: Yoga and meditation can help improve circulation and reduce blood pressure, which can help promote healthy blood flow to the brain. This process can help protect against cognitive decline.
- Reducing depression: Depression is a known risk factor for dementia. Yoga and meditation can reduce symptoms of depression and anxiety, which may help lower the risk of developing dementia.
Yoga and meditation for dementia prevention—these practices have numerous benefits.
- Preventing cholesterol buildup in blood vessels, maintaining normal blood pressure, keeping healthy blood sugar levels, and achieving a healthy weight can help brain health.
- These healthy habits can ensure that the brain receives sufficient oxygen and nutrients to function at its highest possible level.
- By staying healthy, individuals can potentially prevent or delay the onset of dementia.
