A new study has revealed that people showing early signs of dementia wait an average of 3.5 years before receiving an official diagnosis, a delay that could significantly impact treatment and quality of life.
Published in the International Journal of Geriatric Psychiatry, the study reviewed data from 13 previously published studies across Europe, US, Australia, and China, analyzing a combined total of over 30,000 individuals. The findings indicate a global challenge in diagnosing dementia, especially in cases of early-onset and frontotemporal dementia, where the diagnostic delay can extend up to 4.1 years.
Lead author Dr. Vasiliki Orgeta from University College London (UCL) emphasized the urgent need for healthcare systems to address this gap. &ldquo;Timely diagnosis can allow access to therapies that may slow progression and improve quality of life for patients and families,&rdquo; Orgeta stated.
The study also highlights that symptoms such as memory loss, mood swings, confusion, and trouble finding words are often mistaken for normal aging. This misunderstanding, coupled with stigma and limited awareness, causes individuals and families to delay seeking help.
Dr. Phuong Leung, co-author and also from UCL, pointed out that &ldquo;many people simply do not recognize early symptoms, or they avoid medical consultation out of fear or embarrassment.&rdquo;
Experts behind the study are calling for public awareness campaigns to reduce stigma and increase recognition of early signs. They also stress the need for clinician training to ensure early detection and timely referrals.
With over 57 million people currently living with dementia worldwide, and diagnostic rates in high income countries reaching only 50&ndash;65%, the study underlines a critical public health issue. Better education, more proactive screening, and stronger support systems are key to shortening the diagnosis timeline and offering early interventions
