Dementia is a broad term used to describe a range of cognitive impairments that interfere with daily life and activities. In India, dementia affects approximately 3.7 million people, a number that is projected to rise due to an aging population. According to the Indian Journal of Psychiatry, the prevalence of dementia in the Indian population is about 1.8% among individuals aged 60 and above. Despite its growing impact, dementia is surrounded by numerous myths and misconceptions, which can hinder effective diagnosis and treatment. This article aims to clarify 10 common myths about dementia, providing evidence-based facts to promote better understanding and management of this condition.
10 Common Myths About Dementia
Myth 1: Dementia is a Normal Part of Aging
Fact:
Dementia is not a normal part of aging but rather a medical condition caused by diseases that damage the brain. While age is a risk factor, dementia is different from normal age-related memory decline. The Alzheimer’s and Related Disorders Society of India explains that diseases like Alzheimer’s are responsible for the cognitive decline associated with dementia. (Source)
Myth 2: All Dementia is Alzheimer’s Disease
Fact:
Alzheimer’s disease is the most common type of dementia, but it is not the only one. Other forms include vascular dementia, Lewy body dementia, and frontotemporal dementia. The National Institute of Mental Health and Neurosciences (NIMHANS) in Bangalore highlights that each type has distinct symptoms and requires different management strategies. (Source)
Myth 3: Dementia Only Affects the Elderly
Fact:
While dementia is more common in older adults, it can also affect younger individuals, a condition known as early-onset dementia. According to The Times of India, early-onset dementia can begin before the age of 65, though it is less common than late-onset forms. (Source)
Myth 4: Memory Loss is the Only Symptom of Dementia
Fact:
Memory loss is a key symptom, but dementia can also cause difficulties with language, problem-solving, and reasoning, as well as changes in behavior and personality. The Alzheimer’s Association notes that these symptoms vary depending on the type of dementia and the areas of the brain affected. (Source)
Myth 5: Dementia is Caused by Poor Lifestyle Choices
Fact:
Dementia is primarily caused by diseases and conditions that affect the brain, not by lifestyle choices. However, maintaining a healthy lifestyle can reduce the risk of developing dementia. The Indian Journal of Psychiatry emphasizes that genetic factors and age are major risk factors, though a healthy lifestyle may help mitigate some risks. (Source)
Myth 6: There is No Treatment for Dementia
Fact:
While there is no cure for dementia, treatments are available to manage symptoms and improve quality of life. Medications can help with cognitive symptoms, and non-pharmacological interventions such as cognitive therapy can also be beneficial. The Alzheimer’s Disease Research Foundation highlights that early diagnosis and treatment can help slow progression and enhance the patient’s well-being. (Source)
Myth 7: Dementia is the Same as Depression
Fact:
Dementia and depression are distinct conditions. Dementia involves a progressive decline in cognitive function, whereas depression is a mood disorder that can be treated with therapy and medication. The Indian Journal of Psychiatry distinguishes between these conditions, noting that while symptoms may overlap, the underlying causes and treatments are different. (Source)
Myth 8: People with Dementia Cannot Live Independently
Fact:
The ability to live independently depends on the stage of dementia and the individual’s specific needs. Early-stage dementia patients may continue to live independently with appropriate support and adaptations. The Alzheimer’s and Related Disorders Society of India points out that personalized care plans can help maintain independence for as long as possible. (Source)

Myth 9: Dementia is Inherited and Cannot Be Prevented
Fact:
While some types of dementia have a genetic component, not all are inherited. Lifestyle factors, such as cardiovascular health, can influence risk. The Indian Council of Medical Research suggests that while genetics play a role, a healthy lifestyle and mental stimulation may help reduce the risk of developing dementia. (Source)
Myth 10: Dementia Only Affects Memory
Fact:
Dementia affects various cognitive functions beyond memory, including judgment, spatial awareness, and executive functions. The Alzheimer’s Disease International notes that cognitive decline impacts multiple areas, leading to a wide range of symptoms affecting daily life and functionality. (Source)
