With a massive population already living with dementia worldwide, the condition has emerged as one of the leading causes of disability and dependence among older adults. According to the World Health Organization (WHO), dementia is the seventh leading cause of death globally and the number of cases is expected to triple by 2050. Despite its rising prevalence, many people remain unaware of its early symptoms, often mistaking them for normal signs of ageing leading to delayed diagnosis and intervention.What is dementia?Dementia is an umbrella term for a group of disorders that affect memory, thinking, language and daily functioning. It is not a single disease but a set of symptoms caused by various conditions that damage brain cells. While Alzheimer’s disease is the most common cause, other types include vascular dementia, Lewy body dementia, and frontotemporal dementia (FTD).There are several risk factors that can increase the likelihood of developing dementia, including age, hypertension, diabetes, obesity, smoking, alcohol consumption and even depression. Though there is no known cure, timely diagnosis and appropriate medical support can significantly improve the quality of life for patients and their families.Why early detection mattersExperts emphasise that timely intervention is crucial. With proper care, cognitive therapies and medications, doctors can help people living with dementia function more independently and slow down the progression of symptoms. Unfortunately, the early warning signs are often subtle and easy to dismiss as harmless forgetfulness or stress-related behaviour. Recognising them early can make a world of difference.5 worrying signs you shouldn’t ignore1. Misplacing items frequentlyOccasionally forgetting where you kept your keys or glasses is normal. But if someone repeatedly misplaces items in unusual places—like finding their glasses in the fridge or cleaning supplies in the kitchen cabinet—it may be an early sign of dementia. This behaviour reflects disorientation and short-term memory loss, both hallmark symptoms.2. Communication difficultiesA person who was once fluent and articulate may begin to struggle with forming sentences, finding the right words, or following conversations. This can be particularly evident in frontotemporal dementia (FTD), which affects the brain’s frontal and temporal lobes—areas responsible for language and behaviour.3. Memory lapsesForgetting recent events, appointments, or names of familiar people can be a red flag. While mild forgetfulness can be age-related, persistent memory issues that interfere with daily life should prompt a visit to a doctor.4. Sudden mood or personality changesA calm, even-tempered person becoming irritable, anxious, or tearful without any clear reason could be experiencing early emotional changes associated with dementia. Caregivers often notice these subtle shifts before cognitive symptoms become obvious.5. Confusion about time or placeGetting lost on familiar routes, forgetting where one is, or confusing family members are significant warning signs. Such disorientation can escalate quickly and pose safety risks if ignored.A growing concern among younger adultsWhile dementia is most common in people over 65, doctors are observing younger-onset cases, especially with FTD, which can develop in individuals as young as 45. Because the symptoms like personality and behaviour changes, mimic psychiatric conditions such as schizophrenia or aphasia, diagnosis is often delayed.There’s currently no cure for dementia, but early diagnosis can help manage symptoms effectively, plan care better and support families emotionally and financially. If you notice repeated forgetfulness, communication issues or behavioural changes in a loved one, it’s best to consult a doctor or neurologist at the earliest. Awareness, empathy and timely medical attention can go a long way in helping those affected live with dignity and support.
