227,000 people in Japan have ‘Higher Brain Dysfunction’

An estimated 227,000 people in Japan are living with higher brain dysfunction, an “invisible disability” caused by brain damage from strokes or accidents, yet the condition remains poorly understood because its symptoms are not outwardly apparent. As a result, families of those affected often face profound and isolating challenges, including sudden personality changes, emotional instability, and cognitive impairments that others may misinterpret as normal behavior. This lack of visible signs can lead to misunderstanding and insufficient support, leaving caregivers to cope with stress, confusion, and loneliness while navigating daily life alongside their loved ones.
