10 signs of dementia you should never ignore – and the habits you should start today

Dementia refers to a group of conditions that progressively impair memory, thinking, language, and the ability to carry out everyday activities. It is not a normal part of aging, even though the risk increases with age.

Early signs can include memory loss that disrupts daily life, difficulty with planning or routine tasks, confusion about time or place, trouble finding words, misplacing items without retracing steps, and noticeable changes in mood, judgment, or personality. People may also withdraw from social activities.

Although most dementias have no cure, early recognition is important. It allows for proper medical evaluation, better symptom management, and time to plan for future care and decisions, while also helping families prepare and access support.

Healthy habits—such as regular exercise, good sleep, mental stimulation, avoiding smoking, limiting alcohol, and managing nutrient levels—may support brain health.
