A recent study has revealed that people with dementia are typically diagnosed 3.5 years after they first notice symptoms, causing significant delays in receiving the care they need. Common early signs, such as forgetfulness, difficulty finding words, confusion, and changes in mood, can easily be overlooked, making early diagnosis a challenge.

The research, published in the International Journal of Geriatric Psychiatry, found that individuals with early-onset dementia, which affects those under 65, face an even longer wait, with diagnoses taking an average of 4.1 years. Younger people and those with frontotemporal dementia often experience delays in diagnosis, the study showed.

Why Timely Diagnosis Matters

Dr. Vasiliki Orgeta, the lead author of the study and a researcher at University College London (UCL), stressed that early detection of dementia is critical. “A timely diagnosis can help people access treatments sooner and, for some, can allow them to live with mild symptoms before they progress,” Dr. Orgeta explained.

The study reviewed data from more than 30,000 participants across 13 studies conducted in countries including the US, Australia, China, and several European nations. Despite the fact that dementia affects over 57 million people worldwide, it’s estimated that only 50-65% of cases are diagnosed in high-income countries, with the diagnostic rate even lower in many lower-income countries.

Barriers to Early Diagnosis

Dr. Phuong Leung, another researcher from UCL, pointed out that dementia symptoms are often dismissed as a normal part of aging. He also noted that the fear, stigma, and lack of awareness surrounding dementia often discourage people from seeking help early enough.

Dr. Orgeta echoed these concerns, saying that public awareness campaigns are essential to help people recognize the early signs of dementia and reduce the stigma attached to seeking medical advice. “Improving clinician training is also key to making sure symptoms are caught early, leading to better referrals and support for both patients and their families,” she said.

Steps Toward Improvement

The study’s findings underscore the urgent need for better strategies to detect dementia earlier. Experts are calling for:

• Public awareness campaigns to educate people on early dementia symptoms.
• Training for healthcare providers to improve early detection.
• More accessible early interventions and tailored support for individuals and families affected by dementia.

As dementia cases continue to rise globally, addressing these delays in diagnosis is crucial to improving outcomes for those living with the condition. Early intervention can make a significant difference in managing symptoms and improving quality of life.
