New research and expert commentary highlight that lasting low mood and anxiety can be among the first signs of dementia, sometimes appearing before noticeable memory loss. A leading neurologist notes that these subtle emotional changes are often mistaken for normal aging or everyday stress, yet they may indicate developing cognitive decline. In Thailand, with an aging population and rising dementia expectations, recognizing mood-related symptoms is crucial for early intervention.
Data from international studies show mood disturbances in the early stages of dementia. A 2025 study found a strong link between anxiety and depression and early Alzheimer’s disease, even in individuals with mild cognitive impairment. Research into Lewy body dementia also indicates that neuropsychiatric symptoms like anxiety can precede classic memory problems, underscoring how mood and behavior changes reflect underlying brain changes. According to researchers, these findings encourage clinicians to consider dementia when mood shifts occur alongside subtle cognitive clues.
Global guidelines reinforce this perspective. The UK’s National Health Service lists mood changes—such as anxiety, depression, or irritability—as recognized early symptoms, along with memory loss and confusion. The Alzheimer’s Association also cautions against ignoring persistent mood changes, even when memory seems intact.
For Thai readers, these developments carry practical implications. Dementia in Thailand is often underdiagnosed or diagnosed late, partly because families attribute non-memory symptoms to aging or to cultural concepts of elder emotion. In multi-generational Thai households, concerns about family image and “face” may delay conversations about mental health. This makes awareness of the full spectrum of dementia signs essential.
Thai health professionals echo the international message. A geriatrician at a major Bangkok hospital emphasizes that persistent low mood and unexplained anxiety in older adults should prompt assessment, especially when subtle memory changes or confusion are present. Public-health campaigns in Thailand now encourage timely medical consultation when mood shifts accompany cognitive concerns.
Stigma around mental health has historically hindered care in Thailand. As understanding of neurological diseases grows, more Thai families recognize that mood and personality changes can stem from brain changes, prompting a more proactive, medical approach to elder care.
Looking ahead, experts expect dementia screening to become routine in Thailand as the population ages and awareness grows. Mobile health tools and telemedicine are likely to expand access, bringing early assessments to rural communities and underserved areas.
Takeaway for Thai individuals and families: treat persistent low mood and anxiety in older adults seriously, especially when paired with forgetfulness or confusion. Early medical evaluation can identify dementia in its initial stages, enabling timely treatment, support, and access to community resources, including cognitive therapies and caregiver programs.
In short, understanding the full range of early dementia signs—particularly mood and anxiety changes—can make a life-changing difference for Thai families. Health professionals urge vigilance: if an elderly loved one shows sustained sadness, worry, or attitude changes without a clear cause, don’t dismiss it as merely aging. Proactive steps, guided by current research and expert guidance, can improve quality of life and ensure dignified care.
