The COVID-19 pandemic has profoundly affected global mental health, leading to an unprecedented rise in psychological disorders such as anxiety, depression, and post-traumatic stress disorder (PTSD). Social isolation, economic uncertainty, grief from loss, and disruptions to daily life have contributed to increased stress levels and emotional distress across all age groups. Healthcare workers and vulnerable populations have experienced heightened risks of burnout and trauma. Moreover, the pandemic accelerated the adoption of teletherapy and digital mental health solutions, which have improved access but also highlighted disparities in care. Addressing the long-term psychological effects of the pandemic requires comprehensive strategies involving community support, accessible mental health services, and policies aimed at reducing stigma and promoting resilience.
