Alzheimer’s disease is the most common form of dementia worldwide. It happens when brain cells are damaged by abnormal proteins (plaques and tangles), leading to cell death and brain shrinkage.

Alzheimer’s disease impacts memory, thinking, and reasoning skills, gradually making everyday life more difficult. Early recognition of the signs of Alzheimer’s disease means better handling of its progression and planning for the future. This blog explains what to watch for, why you shouldn’t dismiss these changes as “just ageing,” and how to talk about symptoms sooner rather than later.

Alzheimer’s stages and symptoms

Alzheimer’s is often described in stages- from mild through moderate to severe. In early (mild) Alzheimer’s, symptoms might be subtle but are noticeable by close family or the person themselves. In the moderate stage, problems become clearer: assistance is needed with daily tasks, more memory loss shows up, and behaviour changes emerge. In the late stage, the person needs full-time care.

Because the disease evolves slowly, the early thinking and memory changes may be easy to dismiss. Being alert to the early stage means looking past occasional mistakes, especially if they increase, affect daily life, and are accompanied by mood or behaviour changes.

Depression, anxiety, and Alzheimer’s: a complex link

It is common to ask: “Are depression and anxiety early symptoms of Alzheimer’s?”

While mood disorders themselves are not definitive signs of Alzheimer’s, the presence of depression, anxiety, or apathy, accompanied by cognitive change, raises the risk. Emotional changes may come before or along with memory problems. Thus, early mood symptoms combined with memory problems deserve attention.

Why early detection matters

With Alzheimer’s disease, brain changes begin years before the obvious symptoms. If the disease remains undetected, daily life becomes harder, and options for care and support become more complex. According to the Centers for Disease Control and Prevention (CDC), early diagnosis enables individuals to receive the necessary support sooner and plan for their future.

When we say “early signs of Alzheimer’s,” we are talking about more than forgetfulness. We mean changes in judgment, language, mood, and reasoning that interfere with daily functioning.

Common early symptoms of Alzheimer’s

Here are some of the most frequently reported Alzheimer’s symptoms and how they differ from normal ageing:

1. Memory loss that disrupts daily life: One of the clearest symptoms of Alzheimer’s disease is forgetting recently learned information, asking the same question repeatedly, or relying more and more on memory aids. A busy professional might miss a familiar meeting location and later apologise. People with early Alzheimer’s may not realise they’re lost.
2. Difficulty planning or solving problems: Once easy tasks, like balancing accounts, following a recipe, or making a shopping list, become confusing. The issue isn’t occasional mistakes; it’s a pattern of change.
3. Trouble completing familiar tasks: You might recognise this when someone struggles with driving a familiar route, operating a household appliance, or handling their usual financial tasks.
4. Confusion with time or place: Losing track of dates, seasons, or where they are, even in a familiar environment, is a red flag.
5. New problems with language: Mixing up words, pausing mid-sentence, calling things by the wrong name- these are more than “senior moments.” They’re part of the early stage of Alzheimer’s.
6. Decreased or poor judgment: Someone may wear clothes inappropriate for the weather, fall for financial scams, or neglect grooming. These changes may point to Alzheimer’s rather than just busy schedules.
7. Withdrawal from work or social activities: Thinking and remembering become harder, resulting in shying away from hobbies, social events, or work roles they once loved.
8. Mood and personality changes: Depression, anxiety, apathy, unexplained irritability, or confusion may be early behavioural signals of Alzheimer’s.

What to do if you notice early signs of Alzheimer’s

1. Document what you’ve noticed: Note when symptoms started, what changed, and how they impact daily life.
2. Consult a doctor: Share your observations. A cognitive assessment, medical history, and possibly lab tests or brain scans may be recommended. The earlier you start conversations, the better.
3. Review treatable causes: Some conditions—vitamin B12 deficiency, thyroid problems, sleep apnoea—can mimic Alzheimer’s symptoms and are treatable.
4. Support plan: Early diagnosis allows you to make lifestyle adjustments, plan legally and financially, and look into therapies that may slow progression.
5. Stay socially, mentally, and physically active: Good habits make a difference in brain health, even when Alzheimer’s is present.

Conclusion

Recognising early signs of Alzheimer’s is not about fear- it’s about empowerment. Memory lapses alone aren’t enough to diagnose Alzheimer’s, but when they come with trouble planning, mood changes, or withdrawal from activities, the picture changes. If you or a loved one shows the signs and symptoms of Alzheimer’s disease, don’t wait. The sooner you act, the better you can protect the quality of life, plan, and join the next phase of care.

By knowing what to watch for and how Alzheimer’s symptoms evolve, you give yourself and others the best chance of managing the condition with dignity and purpose.
