Introduction

Dementia is a condition that affects memory, thinking, behaviour, and daily functioning. In India, the number of dementia cases is rising due to increased life expectancy, limited awareness, and lifestyle changes. Recognising the early signs of dementia is essential for timely diagnosis and support.

This guide offers Indian families simple and clear information while focusing on dementia and brain health.

What Is Dementia?

Dementia refers to a set of symptoms that affect brain function. It leads to problems with remembering, thinking, decision-making, and daily activities. Alzheimer’s disease is the most common cause of dementia.

Early Signs of Dementia

Memory Problems

One of the earliest symptoms is memory loss that affects everyday life. People may forget recent conversations, repeat questions, misplace items, or forget the names of familiar people.

Difficulty Planning or Solving Problems

Managing money, cooking, understanding bills, or planning daily tasks becomes challenging.

Confusion About Time or Place

People may forget dates, seasons, or where they are, even in familiar places.

Trouble Completing Familiar Tasks

Simple activities like cooking, using a mobile phone, or driving to known locations may feel confusing.

Problems With Speaking or Understanding

They may struggle to find words, repeat sentences, or forget the flow of a conversation.

Poor Judgment

Unexpected decisions such as giving money to strangers, choosing wrong clothes for weather, or risky behaviours may occur.

Mood or Personality Changes

People may become anxious, irritated, withdrawn, or suddenly depressed.

Difficulty Recognising People or Objects
