#Timeblindness

A growing body of scientific research is turning conventional wisdom about chronic lateness on its head: for many, persistent tardiness is not merely a matter of laziness or poor manners but a symptom of an underlying mental health condition known as “time blindness.” The latest analyses from psychiatrists and neuroscientists suggest that time blindness—while not formally categorized in leading diagnostic manuals such as the DSM-5—is a pervasive issue, disrupting lives, careers, and relationships worldwide, including here in Thailand.

Time blindness is gaining recognition as a genuine cognitive difference that affects everyday life. In Thailand, where punctuality is intertwined with respect and reliability, this condition can undermine work, study, and family routines. Time blindness involves difficulty estimating and tracking time, and it often coexists with ADHD, autism, and mood conditions. While not listed in DSM-5, experts say the challenge is real and measurable, influencing employability and daily functioning.

Thai culture places a premium on being on time. For people with time blindness, arriving punctually can feel like an ongoing struggle. Neuroscience points to differences in executive functions, especially the prefrontal cortex, which guides planning and time management. Mental health professionals emphasize that time blindness is not intentional noncompliance but a cognitive difference that affects performance at work and school.
