Learn the early sign
Noticing changes in yourself or your loved ones can feel unsettling, and it’s often hard to know how to respond. You might hesitate to bring up concerns about your own health because speaking them aloud can make them feel more real. Similarly, pointing out changes in another person’s abilities or behaviour may seem uncomfortable, as you may worry about upsetting them. Still, these are important health issues that should be assessed by a medical professional, and taking steps to address them is essential in understanding what’s happening.
Memory loss that interferes with daily life
A hallmark sign of early Alzheimer’s disease is difficulty remembering newly learned information. This may show up as forgetting important dates or events, repeating the same questions, or increasingly depending on notes, devices, or family members for tasks once managed independently.
Problems with planning or problem-solving
Individuals with Alzheimer’s or other dementias may struggle to create or follow plans, especially those involving numbers. They might find it hard to follow a familiar recipe, manage monthly bills, or maintain focus, often taking much longer to complete tasks than before.
Difficulty with familiar tasks
Daily activities can become challenging. Someone may lose track of how to drive to a well-known place, organize a shopping list, or remember the rules of a favourite game.
Confusion about time or place
People may lose awareness of dates, seasons, or the passage of time. They might struggle to understand events that aren’t happening immediately or forget where they are and how they arrived there.
Trouble with vision and spatial awareness
Alzheimer’s can affect visual processing, leading to problems with reading, judging distances, or recognizing colors and contrasts. These changes may cause difficulties with balance or driving.
Language difficulties
Conversation may become harder. A person might stop mid-sentence without knowing how to continue, repeat themselves, or struggle to find the right word. They may misname familiar objects, such as calling a watch a “hand-clock.”
Misplacing items and losing track of steps
Objects may be placed in unusual spots, and the person may be unable to retrace steps to find them. Over time, they might even suspect others of stealing.
Poor judgment
Decision-making may be affected. For example, someone might mishandle money or neglect personal hygiene and grooming.
Withdrawal from social or work activities
Difficulty following conversations can lead to pulling away from hobbies, social gatherings, or work. They may lose interest in activities they once enjoyed or struggle to keep up with their favourite sports or hobbies
Mood and personality changes
Alzheimer’s can bring shifts in mood and behavior. A person may become anxious, suspicious, depressed, or easily upset, especially outside familiar environments.
It is common for age-related changes to be mistaken for early signs of Alzheimer’s disease or other dementias. The table below highlights key differences to aid understanding.
| Area of Change | Alzheimer’s/Dementia | Typical Age-Related Change |
|---|---|---|
| Memory | Frequently forgetting recently learned information, important dates, or events; repeating questions; relying heavily on reminders or others. | Occasionally forgetting names or appointments but recalling them later. |
| Planning & Problem-Solving | Difficulty following a plan, working with numbers, or completing familiar tasks such as recipes or bills; slower concentration. | Making occasional errors when managing finances or household tasks. |
| Daily Tasks | Trouble completing routine activities, such as driving to familiar places or organizing a shopping list. | Sometimes needing help with technology or complex instructions. |
| Time & Place Awareness | Losing track of dates, seasons, or location; confusion about how they arrived somewhere. | Brief confusion about the day of the week, corrected later. |
| Vision & Spatial Skills | Problems judging distance, color, or contrast; difficulty reading or driving. | Vision changes due to conditions like cataracts. |
| Language | Struggling to follow or join conversations; repeating phrases; misnaming familiar objects. | Occasionally searching for the right word. |
| Objects & Belongings | Misplacing items in unusual places and unable to retrace steps; may accuse others of theft. | Misplacing items occasionally but able to retrace steps to find them. |
| Judgment | Poor decision-making, such as mishandling money or neglecting personal care. | Making a poor choice once in a while, e.g., forgetting car maintenance. |
| Social Engagement | Withdrawing from hobbies, work, or social activities due to difficulty following conversations. | Sometimes feeling less interested in social or family commitments. |
| Mood & Personality | Noticeable changes such as confusion, suspicion, depression, anxiety, or irritability in unfamiliar settings. | Preferring routines and becoming irritable when they are disrupted. |
