You can't self-diagnose dementia or anxiety; only a doctor can, but key differences are: dementia involves progressive, irreversible cognitive decline (memory loss, confusion, planning issues) with potential personality changes, while anxiety is about excessive worry, fear, or nervousness that can impair focus but memory loss is usually temporary due to poor concentration, and anxiety symptoms (racing heart, sweating) often resolve, unlike dementia's gradual worsening, though anxiety can be an early sign or symptom of dementia, making professional evaluation essential for accurate diagnosis.
Low mood and anxiety are common early symptoms. People may become anxious about going to new places or meeting others. In some types of dementia, like frontotemporal dementia, early signs can include: changes to behaviour.
Among the several diseases that might mimic dementia symptoms are anxiety, bipolar disorder, heart disease, poor diet, UTIs, and depression. These diseases can produce memory, concentration, confusion, walking, and thinking difficulties that would be misread as dementia.
Unlike people with Alzheimer's, people with depression are usually not disoriented. People with depression have difficulty concentrating, whereas those affected by Alzheimer's have problems with short-term memory. Writing, speaking, and motor skills aren't usually impaired in depression.
Anxiety often occurs early in the course of AD, especially among patients with MCI, mild dementia, or early-onset forms of the disease, and can promote progression and conversion from MCI to dementia.
The "2-finger test" for dementia involves an examiner showing a hand gesture (like interlocking index and middle fingers) and asking the patient to copy it, testing motor skills, visual memory, and coordination, as difficulties can signal early cognitive decline, but it's a screening tool, not a definitive diagnosis, prompting further medical evaluation. Other related tests include finger-tapping and finger-to-nose, looking for hesitation or misjudgment in movement.
Although the early signs vary, common early symptoms of dementia include: memory problems, particularly remembering recent events. increasing confusion.
You Miss Out on Sleep
You do a few things you know you shouldn't -- we all do. But some of those bad habits can take a toll on your brain. For example, lack of sleep may be a cause of dementia, including Alzheimer's disease. It's best to have regular sleeping hours.
When a person notices changes in their memory, often their first thought is of dementia. However, there are many “pseudo dementias, ” or conditions that are often mistaken for dementia, including mental health issues like depression, anxiety, and post-traumatic stress disorder (PTSD).
Although depression may occur only once during your life, people typically have multiple episodes. During these episodes, symptoms occur most of the day, nearly every day and may include: Feelings of sadness, tearfulness, emptiness or hopelessness. Angry outbursts, irritability or frustration, even over small matters.
Key Differences Between Anxiety and Dementia
However, there are clear differences. Memory and cognition: Anxiety does not cause memory loss, but excessive worry can make it hard to focus, whereas dementia leads to significant and progressive memory decline.

To reduce anxiety naturally, focus on lifestyle changes like regular exercise, a balanced diet, and good sleep, alongside mental techniques such as mindfulness, deep breathing, and challenging negative thoughts.

There is no known cure, but early diagnosis and treatment can lead to better quality of life. Stay healthy with a good diet and regular exercise. Stay away from alcohol and other substances that may affect memory, thinking, and behavior.
Common changes in behaviour
One of the reasons dementia patients often have anxiety themselves is because they cannot comprehend what's going on, and their confusion isn't something that goes away. This is different from anxiety, where the person is aware of the feeling that they're losing their mind, which often indicates that they aren't.
The 10 warning signs of dementia include memory loss, difficulty with familiar tasks, confusion about time/place, trouble with language, poor judgment, misplacing things, personality changes, loss of initiative, and problems with visual/spatial skills, requiring professional assessment to distinguish from normal aging.
They also found that breakfast skippers were more likely to experience cognitive decline and signs of neurodegeneration during the study period. Ultimately, the researchers concluded that “breakfast skipping was linked to an increased risk of long-term cognitive decline and neurodegeneration among older adults.”
The cause of roughly 70% of all dementia cases is Alzheimer's disease, a progressive brain disorder characterized by the buildup of amyloid plaques and tau tangles, leading to memory loss and impaired thinking that interferes with daily life, making it the most common form of dementia.
Our results confirm that vitamin D deficiency is associated with a substantially increased risk of all-cause dementia and Alzheimer disease.
Sign 8: Changes in mood, personality and behaviour
For example, they may quickly become tearful or upset for no obvious reason. They may be confused, fearful, suspicious and withdraw from others. They may act differently from what is normal for them.
Even though a person with dementia may end up sleeping more than a typical person of their age – even as much as 14–15 hours a day – it is unlikely to all be good quality sleep. Sleeping a lot can also be influenced by people's sleeping patterns before they had dementia, as some people need more sleep than others.
