Dementia

Several factors are known to increase the likelihood of developing dementia, including:

Age

The risk of dementia increases with age, particularly after the age of 65. However, it is important to note that dementia is not a natural part of aging.

Family history

If a close family member has dementia, there is a higher chance of developing it due to shared genetic factors.

Chronic health conditions

Diseases like diabetes and hypertension can elevate the risk of dementia.

Nutritional deficiencies

A lack of essential vitamins, especially the vitamin B complex, can heighten the risk of dementia.

Alcohol misuse

Heavy alcohol consumption is a significant risk factor for dementia.

Medications

Certain medications, including antidepressants like amitriptyline, anti-allergy drugs such as diphenhydramine, benzodiazepines, anticholinergics, and opioids, can increase the risk of dementia.

To assess a person with memory loss, a doctor gathers a detailed history of the symptoms’ onset, examines family history, and conducts physical and cognitive tests to evaluate the patient’s neurological and psychological condition. Additional lab tests and imaging may be needed to pinpoint the underlying cause of dementia. These include:

Blood tests

• Thyroid profile: Detects thyroid imbalances that may cause cognitive problems similar to dementia.
• Vitamin B-12: Identifies B-12 deficiency, which can lead to memory issues and neurological decline.
• Vitamin D (25-OH): Assesses deficiencies that could contribute to cognitive impairment.
• Complete blood count (CBC): Checks for infections or anemia that may affect brain function.
• Erythrocyte sedimentation rate: Detects inflammation that may be related to dementia-like symptoms.
• Protein electrophoresis CSF: Identifies abnormal proteins in cerebrospinal fluid, associated with neurodegenerative diseases.

Imaging studies

• CT scan (head): Provides clear images of the brain to detect shrinkage, strokes, or structural abnormalities linked to dementia.
• MRI brain: Offers detailed images of brain tissue to identify atrophy, strokes, or other changes associated with dementia.
• MR angiography brain: Examines brain blood vessels for blockages or reduced blood flow, which can contribute to vascular dementia.
• CT angiography brain: Uses contrast dye to visualize blood vessels and detect vascular issues that may lead to dementia symptoms.

Other tests

Additional tests such as EEG (Electroencephalography), ECG (Electrocardiography), and Echocardiography may be conducted to evaluate brain and heart activity.

While it may not be possible to fully prevent certain types of dementia, adopting a healthy lifestyle can help reduce the risk of dementia linked to poor lifestyle choices. The key habits for prevention are:

Fuel your brain

Consume a balanced diet rich in essential vitamins and minerals to support brain function.

Stay active, stay alert

Engage in regular physical exercise for overall health, and keep your mind active with activities such as puzzles, reading, and other brain-stimulating exercises to promote cognitive health.

Manage your health

Properly manage chronic conditions like diabetes, high blood pressure, and thyroid disorders through appropriate treatment.

Prioritize rest

Maintain a consistent sleep routine to ensure deep, restorative sleep that supports brain health.

Specialists to Consult

Often, family members or loved ones notice early signs of dementia. If someone frequently forgets important tasks or shows changes in behavior, speech, and cognitive abilities, it’s crucial to have them evaluated for dementia. The following specialists can help diagnose and manage dementia:

• General physician
• A general physician assesses overall health, conducts initial evaluations, and refers to specialists for further diagnosis and treatment.
• Neurologist
• A neurologist specializes in diagnosing and managing neurological conditions, including dementia, by identifying brain-related causes.
• Neuropsychologist
• A neuropsychologist conducts cognitive testing to assess memory, thinking, and behavior, helping track dementia progression.
• Psychiatrist
• A psychiatrist addresses any psychiatric symptoms related to dementia and prescribes medications to manage mood and behavior.

Dementia treatment primarily focuses on supportive care and addressing any treatable underlying causes. Treatment options include:

Medications to enhance cognitive function

• Acetylcholinesterase inhibitors: These drugs, such as Donepezil, Galantamine, and Rivastigmine, help manage symptoms but do not halt disease progression.
• Nerve-protecting medications: These help nourish nerve cells and protect them from damage, improving cell survival, with Citicoline being an example.
• N-Methyl-D-Aspartate (NMDA) agonists: These reduce glutamate activity to control symptoms, such as Memantine.
• Antioxidants: Drugs like Coenzyme Q10 and Ginkgo biloba combat free radicals, which can contribute to memory decline.
• Nootropic drugs: These, like Piracetam, influence certain brain receptors to improve memory and mental clarity.
• Cyclooxygenase (COX) inhibitors: Medications like Ibuprofen reduce pain and inflammation, protect neurons, and may alleviate symptoms.
• Statins: These drugs, such as Atorvastatin, help treat dementia related to blood vessel blockages by reducing these blockages and improving symptoms.

Medications to manage anxiety and improve sleep

• Selective serotonin reuptake inhibitors (SSRIs): Medications like Fluoxetine and Sertraline treat depression and anxiety.
• Benzodiazepines: Drugs such as Lorazepam offer short-term relief for anxiety.
• Antipsychotics: Medications like Quetiapine manage irritability or aggression.

Medications for reversible causes of dementia

• Supplements: Dementia caused by nutritional deficiencies can sometimes be reversed with vitamin supplements.
• Antidiabetic and antihypertensive drugs: Managing diabetes with oral hypoglycemics or insulin and hypertension with antihypertensives is essential if these conditions contribute to dementia.
• Antibiotics and anti-inflammatory drugs: Infections or inflammation that cause dementia should be treated with the appropriate antibiotics and anti-inflammatory medications.

Dementia is a progressive condition that worsens over time. While current treatments can slow down the disease, they cannot halt its progression. As dementia advances, it may lead to the following complications:

• Safety concerns: People with dementia are at higher risk of accidents, even during daily activities like walking or cooking.
• Personal hygiene: In the later stages, individuals may have difficulty with basic hygiene tasks such as bathing, grooming, and using the restroom.
• Nutritional difficulties: Advanced dementia can cause people to forget to eat or lose interest in food, leading to malnutrition.
• Choking or aspiration: Difficulty swallowing food can result in choking or aspiration, potentially leading to pneumonia.

While alternative therapies may help manage dementia symptoms, they should not replace traditional medical treatments. Some therapies that may offer benefits include:

Exercise and Yoga

• Gentle exercises can help enhance mood, reduce anxiety, and maintain physical activity. Activities such as home-based aerobics, dancing, light weight lifting, and yoga (including Pranayama) are effective.

Physiotherapy and Occupational Therapy

• Physiotherapists or occupational therapists may recommend home or workplace modifications to ensure safety and prevent falls.

Massage Therapy and Aromatherapy

• These therapies can promote relaxation and may help alleviate some symptoms of dementia.

Ayurveda

• In Ayurveda, dementia is referred to as Smrutibuddhirhass. Treatments like Panchkarma and herbs such as Shankhpushpi, Guduchi, Brahmi, Ashwagandha, and Shatavari may help manage dementia symptoms.
