Introduction
Mental health disorders affect millions of people worldwide and have significant impacts on quality of life. According to the World Health Organization (WHO), over 280 million people globally suffer from depression, and anxiety disorders affect approximately 301 million individuals. Post-Traumatic Stress Disorder (PTSD) is also prevalent, with around 3.6% of the global population experiencing it at some point in their lives (National Institute of Mental Health, 2023). These conditions can be debilitating but are treatable with the right interventions.

- Fatigue and lack of motivation
Causes and Risk Factors
- Genetic and Biological Factors: Family history of mental illness can increase susceptibility.
- Environmental Triggers: Stressful events, trauma, abuse, financial instability.
- Chemical Imbalances: Disruptions in neurotransmitters (serotonin, dopamine, norepinephrine) contribute to mood disorders.
- Lifestyle Factors: Poor diet, lack of exercise, substance abuse, and sleep deprivation worsen symptoms.

Advances in Research and Treatment
- Ketamine Therapy: Research shows ketamine infusion can rapidly reduce symptoms of depression (Johns Hopkins University, 2023).
- Psychedelic Therapy: Studies on MDMA and psilocybin show promising results in treating PTSD (MAPS, 2023).
- AI in Mental Health Care: Machine learning is helping diagnose mental disorders earlier (MIT, 2023).
- Teletherapy & Digital Mental Health Apps: Increased access to mental health care through online therapy platforms.
Conclusion
