Dementia is a progressive neurological condition that affects memory, thinking, language, behaviour, reasoning, and the ability to perform everyday activities independently. While occasional forgetfulness can be a normal part of ageing, persistent memory loss, confusion, difficulty communicating, or noticeable changes in behaviour should never be ignored.
Although dementia is more common in adults over the age of 65, it can also occur in younger individuals. Early diagnosis is essential, as timely treatment and supportive care can help slow disease progression, manage symptoms, and improve quality of life.
Dr. (Prof.) Kunal Bahrani, an experienced neurologist in Faridabad, provides comprehensive evaluation and evidence-based dementia care with a focus on accurate diagnosis, personalized treatment, cognitive support, and long-term neurological management.
What is Dementia?
Dementia is not a single disease but a group of conditions caused by damage to brain cells that interfere with communication between different areas of the brain. This damage affects memory, thinking, language, judgement, behaviour, and problem-solving abilities.
Symptoms usually develop gradually and worsen over time, affecting a person’s independence and daily functioning.
It is important to understand that dementia is not a normal part of ageing. While advancing age increases the risk, many older adults never develop dementia.
Types of Dementia
Several neurological conditions can lead to dementia. Identifying the underlying cause is important because treatment and progression vary between different types.
Alzheimer’s Disease
Alzheimer’s disease is the most common cause of dementia, accounting for the majority of cases. It usually develops after the age of 65, although early-onset Alzheimer’s disease may occur in people in their 40s or 50s.
Early symptoms often include short-term memory loss, difficulty finding words, and problems with planning or decision-making.
Vascular Dementia
Vascular dementia develops due to reduced blood flow to the brain, often following one or multiple strokes or chronic blood vessel disease.
Risk factors include:
- High blood pressure
- Diabetes
- High cholesterol
- Heart disease
- Smoking
Frontotemporal Dementia (FTD)
Frontotemporal dementia primarily affects the frontal and temporal lobes of the brain.
Patients often experience:
- Personality changes
- Poor judgement
- Socially inappropriate behaviour
- Language difficulties
- Emotional changes
Memory loss may be less prominent during the early stages compared to Alzheimer’s disease.
Symptoms of Dementia
Symptoms vary depending on the underlying cause and stage of the disease.
Common symptoms include:
- Progressive memory loss
- Difficulty finding words
- Problems with communication
- Confusion about time or place
- Difficulty performing familiar tasks
- Poor judgement and decision-making
- Personality or behavioural changes
- Reduced language skills
- Misplacing objects frequently
- Difficulty recognising familiar people
- Reduced problem-solving ability
- Visual and spatial difficulties
- Loss of independence in daily activities
As dementia progresses, patients may require increasing assistance with personal care and routine activities.
Dementia occurs when nerve cells in the brain become damaged or die, disrupting communication between different brain regions.
Common causes include:
- Alzheimer’s disease
- Stroke and vascular disease
- Parkinson’s disease
- Lewy body disease
- Frontotemporal degeneration
- Brain infections
- Head injuries
- Certain vitamin deficiencies
- Thyroid disorders
- Rare inherited neurological disorders
Some conditions that resemble dementia are reversible when diagnosed and treated early.
Risk Factors
Factors that increase the risk of dementia include:
- Increasing age
- Family history
- High blood pressure
- Diabetes
- High cholesterol
- Smoking
- Obesity
- Cardiovascular disease
- Physical inactivity
- Excessive alcohol consumption
Managing these risk factors may help reduce the likelihood of developing certain forms of dementia.
How is Dementia Diagnosed?
Early diagnosis allows timely treatment and better long-term planning.
Dr. (Prof.) Kunal Bahrani performs a detailed neurological assessment that may include:
- Comprehensive medical history
- Neurological examination
- Memory and cognitive assessment
- Behavioural evaluation
- Blood investigations
- MRI Brain
- CT Brain (when indicated)
- Neuropsychological testing (if required)
These investigations help determine the cause of memory impairment and rule out treatable conditions.
Dementia Treatment
Although there is currently no cure for most forms of dementia, treatment can significantly improve symptoms, preserve independence, and enhance quality of life.
Treatment is individualized according to the underlying diagnosis and disease stage.
Medications
Medications may be prescribed to improve memory, support cognitive function, and manage behavioural or psychological symptoms when appropriate.
Cognitive Rehabilitation
Memory exercises, cognitive stimulation, and structured daily activities help patients maintain mental function for as long as possible.
Lifestyle Modifications
Patients are encouraged to:
- Maintain regular physical activity
- Follow a balanced diet
- Stay socially active
- Keep mentally engaged
- Control blood pressure, diabetes, and cholesterol
- Get adequate sleep
Family Support and Counselling
Dementia affects both patients and caregivers.
Education regarding disease progression, home safety, behavioural management, and long-term care planning is an important part of treatment.
When Should You Consult a Neurologist?
Consult a neurologist if you or a family member experiences:
- Persistent memory loss
- Repeatedly asking the same questions
- Difficulty recognising familiar people
- Personality or behavioural changes
- Confusion about time or place
- Difficulty speaking or understanding conversations
- Problems managing finances or daily activities
- Frequent disorientation
- Sudden worsening after a stroke
Early neurological evaluation helps identify the cause and initiate appropriate treatment.

Frequently Asked Questions
Is dementia a normal part of ageing?
No. Although dementia becomes more common with age, it is not a normal part of growing older. Persistent memory or thinking problems should always be medically evaluated.
Can dementia be cured?
Most forms of dementia cannot currently be cured. However, early diagnosis and treatment can help slow progression, manage symptoms, and improve quality of life.
What is the most common type of dementia?
Alzheimer’s disease is the most common cause of dementia worldwide.
Can younger people develop dementia?
Yes. Early-onset dementia can occur before the age of 65, although it is less common.
Can dementia be prevented?
Not all cases can be prevented, but controlling blood pressure, diabetes, cholesterol, maintaining regular exercise, eating a healthy diet, and staying mentally active may help reduce the risk.
