The Signs of Dementia

signs of dementia

Dementia is a general term for a decline in mental ability due to disease, injury, or old age. Symptoms of dementia can vary from person to person and cause changes in mood and personality.

There are many different types of dementia, and the symptoms can vary depending on the cause, too. However, there are some common signs that may be indicative of the condition.

1. Memory loss

One of the most common signs of dementia is memory loss. This can include forgetting recent events, difficulty retaining new information, or asking the same questions repeatedly. If you notice you or someone you love is having trouble with memory, it’s important to consult a doctor.

Additionally, memory loss can also manifest as changes in familiar surroundings. For instance, a person with dementia may get lost easily, or have trouble finding their way home.

2. Changes in mood and behavior

Dementia can cause changes in mood and behavior. A person with dementia may become easily agitated, anxious, or depressed. They may also act out in ways that are out of character for them, such as becoming aggressive or violent.

In this case, it’s best to try and stay calm, avoid arguing, and provide support. If the person with dementia is exhibiting disruptive behaviors, it may be best to consult a professional for help so you can avoid these situations in the future.

3. Difficulty communicating

Individuals with dementia may have trouble finding the right words to express themselves, or they may become confused during conversations. They may also have trouble reading or writing.

When people notice this symptom, they can often get frustrated with their loved ones. While it’s easy to lash out, patience and education are keys to keeping a positive relationship. So, if you’re wondering what should you not say to someone with dementia in this situation, it’s best to avoid phrases like “You’re wrong,” “Remember this,” or “What did you just say?”

4. Decreased motivation

A decrease in motivation is another one of common signs of dementia. A person with dementia may no longer take part in activities they once enjoyed, or they may have trouble completing everyday tasks.

If you notice this symptom, it’s important to be supportive and understanding. Encourage the person with dementia to stay active, and help them out as much as you can so they don’t become overwhelmed.

5. Changes in sleeping habits

Dementia can also cause changes in sleeping habits. A person with dementia may have trouble falling asleep or staying asleep. They may also sleep during the day and be awake at night.

If you notice this symptom, it’s important to create a routine and stick to it as much as possible. This can help the person with dementia feel more comfortable and may help improve their sleep habits.


These are just a few of the top signs of dementia. If you notice any of these symptoms in yourself or someone you love, it’s important to consult a doctor. Early diagnosis and treatment is essential for managing the condition and preserving the quality of life.
