What Are the Early Signs of Dementia? How to Recognise Them

TABLE OF CONTENTS
Dementia affects people of all ages, not just the older adults. Most cases occur in people over 65, but symptoms can appear in someone's 30s, 40s, or 50s. This reality makes early detection a vital part of healthcare at any age.
A person's memory issues, growing confusion, changes in personality, and struggles with daily tasks could point to something serious. These changes happen slowly, and many people mistake them for typical signs of ageing. This blog helps you identify common causes of dementia and its early warning signs that work as reliable indicators.
Signs of Dementia
People with dementia typically notice memory problems first. They might not remember recent conversations or find it hard to locate everyday items. These memory issues affect daily life more severely than occasional forgetfulness. Other signs and symptoms of dementia include:
Disorientation about time and place shows up as confusion. A person might lose track of dates or seasons. They could find themselves standing in familiar places without knowing how they got there or how to return home.
Several signs point to mood and behaviour changes:
Unexpected mood swings that happen without reason
Pulling away from social activities and family events
Growing anxious in new situations
No longer enjoying favourite activities
Acting in ways that don't match their usual personality
Simple everyday tasks become challenging as the condition progresses. Someone might struggle to follow a familiar recipe, forget their favourite card game's rules, or have trouble paying household bills.
Language problems surface when people start using unusual words for everyday objects. They might call a watch a "hand clock" or struggle to find the right words during conversations. This often leads to frustration and less communication with others.
Simple and complex tasks become harder as problem-solving abilities decline. Forgetting passwords, misplacing items often, or handling money becomes a real challenge. Poor decisions about finances or personal care also become noticeable.
Common Causes of Dementia
Here are some common dementia causes:
Genetic Factors: Family history increases the susceptibility to dementia
Alzheimer's Disease: The most common cause due to brain cell damage
Vascular Dementia: Reduced blood flow to the brain
Lewy Body Dementia: Protein deposits affecting brain function
Parkinson's Disease: Brain degeneration over time
Frontotemporal Dementia: Damage to frontal and temporal brain lobes
Head Injuries: Traumatic brain injuries increase risk
Stroke: Brain damage from blocked or burst blood vessels
Brain Infections: Meningitis or encephalitis
Vitamin Deficiencies: Lack of B12 or folate
Thyroid Disorders: Hormonal imbalances affecting brain function
Alcohol Abuse: Chronic excessive drinking leads to brain damage
10 Ways to Prevent Dementia
Research shows that lifestyle changes can prevent dementia. People could avoid or delay up to 40% of dementia cases by changing their daily habits.
Exercise Regularly
Physical activity is one of the most easy to inculcate and effective ways to lower dementia risk. Active people have a 20% lower chance of developing dementia compared to inactive ones. The brain gets optimal protection from 150 minutes of moderate-intensity aerobic activity in a week combined with strength exercises.
Maintain a Healthy Diet
The MIND diet protects brain health by combining Mediterranean and DASH eating patterns. This diet focuses on:
Fruits, vegetables, and whole grains
Fish rich in omega-3 fatty acids
Healthy fats like olive oil
Limited processed foods and salt
Manage Blood Pressure and Cholesterol
Midlife blood pressure problems substantially raise dementia risk. Proper cholesterol management could prevent dementia. Research shows that statins lower dementia risk by about 20%.
Quit Smoking
Brain health improves right after quitting smoking. Smokers have a 30% higher chance of developing dementia and face a 40% higher risk of Alzheimer's disease.
Limit Alcohol Intake
Heavy drinking disrupts brain health. People who drink more than 14 units weekly may experience reduced brain volume and higher dementia risk. The brain's white matter volume decreases even with moderate drinking. Note: No amount of alcohol is safe for brain.
Other Measures
Scientists have found several ways to lower your dementia risk beyond changing your lifestyle. New research shows these prevention steps are significant.
Get Enough Sleep
Your sleep quality affects brain health. People who sleep less than five hours each night double their risk of developing dementia. A good night's sleep of six to eight hours lets your brain clear out harmful proteins that build up during the day.
Challenge Your Brain
Brain training benefits your cognitive health. People who involve themselves in brain-stimulating activities have a 29% lower risk of dementia. You can try these effective brain exercises:
Learning a new language or musical instrument
Playing board games or solving puzzles
Reading and writing
Taking adult education classes
Stay Socially Active
Social connections are vital to brain health. Research shows active social life can delay dementia onset by five years. Your cognitive function stays sharp when you join community activities and build strong relationships.
Protect Your Hearing
Hearing aids cut cognitive decline by almost 50% over three years in high-risk adults. People who use hearing aids have fewer memory problems and think more clearly.
Manage Stress
High cortisol levels from long-term stress can damage brain cells in the hippocampus. Your brain health and memory improve when you practise stress management techniques like meditation, deep breathing, or relaxation.
Conclusion
Knowing and spotting dementia's early signs enables people to act faster. Warning signs range from memory issues to behavioural changes. These symptoms develop slowly but need attention once they start affecting daily activities.
Age is a significant risk factor, but people can fight dementia through lifestyle choices: regular exercise, healthy eating habits, and good blood pressure management help. Quality sleep, brain exercises, and social activities reduce the risk.
Early detection gives people the best chance to manage dementia well. Anyone who notices these signs should talk to their doctor right away. Preventive steps combined with medical guidance create the most vigorous defence against cognitive decline.
Brain health improves when people stay informed about dementia. This is a vital step forward. Knowing these signs and preventive steps helps build a proactive approach to cognitive wellness, whether someone worries about their own risk or takes care of a family member.
FAQs
What are the common symptoms of dementia?
The following are some common symptoms of dementia:
Memory loss- affecting daily life
Difficulty finding words while speaking
Confusion with time and place
Trouble solving problems or planning
Misplacing items frequently
Poor judgment and decision-making
Mood swings or personality changes
Difficulty recognising familiar people
Trouble following conversations
What are the common causes of dementia?
The following are some common causes of dementia:
Hereditary reason
Head injury
Brain infection
Reduced blood flow to the brain
Stroke
Alzheimer's disease
Parkinson's disease
Alcohol abuse
Is Alzheimer's disease the same as dementia?
People often mix up these terms, but they mean different things. Alzheimer's disease is just a dementia type that makes up 60-80% of all cases. You'll find other types, like vascular dementia and frontotemporal Dementia, and each needs its own treatment approach.
Does having a family member with dementia mean I will get it?
Genetics play a much smaller role than most people think. The numbers tell us that genes cause less than 5% of Alzheimer's cases. Genetics is just a risk factor among many, and you can take steps to lower your overall risk.
Can doctors definitively diagnose dementia?
Your family doctor can give you a proper diagnosis after running detailed assessments. The evaluation process includes:
Cognitive testing
Family interviews
Physical examinations
Brain imaging
Blood tests
Is there a cure for dementia?
Scientists haven't found a cure for Dementia or Alzheimer's disease yet. Research teams around the world keep making new discoveries about these conditions. Right now, symptoms can be managed through various treatments and lifestyle changes.
