Dementia: Causes, Prevention, and Treatment Options Explained

What would you do if you lost your memory for a day? Imagine your loved ones’ familiar faces suddenly becoming strangers and the place you’ve called home for decades feeling foreign. It sounds like a scene from a film, doesn’t it? But for millions living with dementia, this is their reality. 

In this blog, we’ll discuss symptoms, causes, prevention, treatment options, and more.

 How does dementia start?

 Dementia is not a specific disease but a general term used to describe a group of diseases and illnesses that start affecting a person’s Memory, thinking, language, coordination, mood, and Social abilities.

 A 2023 study by the Alzheimer’s Association states that in India, the prevalence of dementia for adults age 60 or older is 7.4%. About 8.8 million Indians aged 60 are living with dementia. It can have an impact on cognitive abilities and behaviour that interfere with a person’s ability to maintain their day-to-day activities. 

 What are the 10 warning signs of dementia?

 Recognising the signs and symptoms of dementia can significantly improve both quality of life and treatment. Here are ten key warning signs and symptoms:

 1. Memory loss: This is the most common early sign of dementia, where the patient might forget recently learned information. Other signs may include forgetting dates or events, asking the same questions repeatedly, and highly depending on memory aids such as notes, electric devices, or family members to remember things.

2. Difficulty completing daily tasks: A person with dementia may find it difficult to carry out a task that he was doing at ease, such as driving to a familiar place, organising a grocery list or remembering the rules of a favourite game.

3. Confusion about the date and time: People with dementia may struggle to keep track of the date, month, or passage of time. They might also forget their current location and how they arrived there.

4. Visual disturbances: Patients with dementia can have visual disturbances, which can affect their balance and reading ability. This can also affect their driving ability, as they can have trouble judging distance and colour contrast.

5. Problems with words: Difficulties in writing and speaking can arise, including problems with following or joining conversations and expressing thoughts clearly.

6. Misplacing things: This may occur more commonly when the person puts their stuff in unusual places.

7. Poor judgment: People can experience poor judgment or decision-making when dealing with money or need to be more attentive to daily tasks.

8. Difficulty with Coordination and Motor Functions: Problems with coordination and motor skills may increase, affecting tasks like using utensils, dressing, or walking steadily.

9. Avoiding social interaction: Difficulty keeping track of plans or engaging in or following conversations, which may lead to social withdrawal.

10. Changes in mood and personality: people with dementia can get confused, stressed, depressed and anxious, and there will be changes in mood and mental wellness.

What are the most common causes of dementia?

Researchers believe various risk factors, such as genetics, habits, and behaviours, cause Alzheimer's disease and other types of dementia. Some of the potential causes are as follows:

• Age: Aging is considered to be the greatest risk factor for dementia. While age increases the risk, it is not a direct cause. Most individuals aged 65 or older are affected with dementia.
• Genes: Certain genetic mutations are linked to an increased risk of developing Alzheimer’s disease and other forms of dementia. For example, the presence of the APOE ε4 allele is associated with a higher risk of Alzheimer’s.
• Family history: A 2021 study by the National Library of Medicine suggests that a person with a family history is at higher risk of developing dementia.
• Head injury: Head injury has a great link to developing dementia in future. Try to be safe by putting on your seat belts and helmets.
• Vascular Health: Conditions that affect blood vessels, such as high blood pressure, diabetes, and high cholesterol, can cause vascular dementia.

What are the stages of dementia?

 Dementia progresses through several stages, each with different characteristics and care needs:

• Early Stage: These are usually mild and may include loss of memory and difficulty in completing daily tasks. A person can’t perform most tasks alone; however, they may require help from time to time.

• Middle Stage: Cognitive decline becomes more noticeable, with increased difficulty in communication, memory, and carrying out daily tasks. As daily activities become difficult, they would require assistance with personal care.

• Late Stage: The later stages are characterised by the inability to speak, severe deterioration of mental and physical functions, and the need for constant supervision. This is normally the final stage. The primary objective is to make the patient as comfortable as possible by taking care of them.

What are the ways to prevent dementia?

There are no sure ways to prevent dementia, but there are certain lifestyle changes that can reduce the risk of acquiring the disease. A 2023 study by JAMA states that being sedentary can increase the risk of dementia. Adopting a proactive approach can help prevent dementia.

• Healthy lifestyle: Eating a healthy diet that includes fruits, vegetables, whole grains, and lean proteins supports overall brain health. Quit smoking and limit alcohol intake, as they can increase the risk of dementia.
• Regular Exercise: Physical activity, such as walking, swimming, or cycling, helps maintain cardiovascular health and clear blood vessels without cholesterol build-up. It also maintains normal blood pressure, which is linked to a lower risk of developing dementia. Exercise can also enhance cognitive functions.
• Mental Stimulation: Engaging in activities like puzzles, solving quizzes, and learning new skills can keep the brain active and potentially delay cognitive decline.
• Social Engagement: Staying socially active and maintaining strong relationships can help preserve cognitive function and reduce the risk of dementia. Social interactions can provide mental stimulation and emotional support.
• Chronic Disease Management: Effectively managing chronic health conditions such as diabetes and hypertension can significantly reduce the risk of vascular dementia and overall cognitive decline.

What are the most effective drugs for dementia?

 Medication cannot cure dementia but can be used to control the symptoms. The best medicine for dementia care include
 

• Cholinesterase inhibitors: Such as donepezil, galantamine, and rivastigmine, slow the breakdown of a brain chemical involved in memory and judgment, enhancing cognitive function.
• Memantine: Commonly prescribed with donepezil as a combination to treat moderate to severe dementia. Antidepressants such as selective serotonin reuptake inhibitors (SSRIs) can be prescribed to improve the overall mood of the person.
• Antipsychotic medicines: Such as olanzapine, risperidone, and aripiprazole, can help control aggression, agitation, delusions and hallucinations.

What therapy is best for dementia?

These strategies may help stimulate your loved one’s memory and cognitive abilities. They might also bring joy and enhance their daily experience. It’s important to choose activities that uplift their spirits and contribute positively to their quality of life, ensuring they don’t become frustrated or overwhelmed in the process.

1. Reminiscence therapy: People talk about events and things about their past, such as favourite music, school days, favourite places, holiday spots and photos.

These can improve the person's mood and cognitive behaviour. The therapist can organise this one-on-one or in a group.

2. Cognitive stimulation therapy (CST): Therapists use CST to improve some symptoms of dementia, such as quality of life, memory, anxiety and depression symptoms, problem-solving skills and communication abilities.

 CST may include a variety of exercises and activities, such as  

• Music Therapy Sessions
• Memory Recall Games
• Storytelling and Creative Writing
• Cooking or Meal Preparation
• Interactive Digital Games
• Movement and Dance Exercises
• Mindfulness and Relaxation Techniques

3. Reality orientation training: The therapist discusses the current happenings surrounding the person, the Current date and time and basic details like name, place and daily routines.

Personal Journeys

Chris Hemsworth, the Australian actor known for his role as Thor, has shared how his father Craig's Alzheimer's diagnosis has shaped his views on health and wellness. He states, “It's a difficult thing to navigate, particularly for the family. It's such a complex disease, and there's no real cure or solution yet. It’s challenging and emotional, but we have to keep pushing forward and supporting each other. Despite the struggles, staying hopeful and united can make a big difference." Despite the difficulties, Hemsworth’s message underscores the power of hope and unity in overcoming challenges.
