Nearly 94% of tuberculosis (TB) patients in an Indian study conducted in Bengaluru reported anxiety symptoms, while 77.3% showed signs of depression. The findings focus on the mental health toll that comes with TB. It also sheds light on the need to include psychological support in routine treatment of tuberculosis.The cross-sectional study, conducted with 66 adults at the Yeshwanthpur Tuberculosis Unit in Bengaluru, found that 56.1% had moderate to severe anxiety symptoms, while 46.9% had moderate to severe depressive symptoms. Nearly half of the participants experienced symptoms of both conditions. The study was conducted by Dr. Pavithra Cheluvaraj, Dr. Vishnu C. Sudhakaran, Dr. Babitha Rajan and Anjana Sasikumar Nair from the Department of Community Medicine at Ramaiah Medical College. The researchers examined the patients using the Patient Health Questionnaire-9 (PHQ-9) and the Generalised Anxiety Disorder-7 (GAD-7) scales. Why Are TB Patients May Experience Anxiety And Depression?Stigma linked with TB, fear of transmitting the infection to family members and existing health conditions may contribute to anxiety and depression among patients, Dr. Pavithra told Bangalore Mirror.TB treatment can also entail a prolonged course of medication and regular follow-up. Psychological distress may make it harder for patients to continue treatment or seek timely care.According to Dr. Pavithra, anxiety and depression if left untreated could affect the course of TB treatment. Patients experiencing psychological distress may delay starting treatment or stop taking their medication, which could compromising recovery and increasing the risk of drug resistance.“If there is delay in diagnosis or treatment, the person can spread the disease,” she said.Also read: You May Be Carrying TB, And Not Know Until It Gets Worse How Was Mental Health Assessed In The Study?The researchers used two standardised screening tools to assess symptoms of depression and anxiety.The PHQ-9 measures depressive symptoms, while the GAD-7 tests for symptoms of anxiety. The study found that 51 of the 66 participants had symptoms linked with depression, and 62 had symptoms that indicated anxiety.Moderate to severe symptoms were found in 31 participants for depression and 37 for anxiety. These screening results indicate the need for further clinical assessment. The findings are merely observations and they do not mean that every participant had a confirmed psychiatric diagnosis of anxiety and depression.Additionally, the study was based on 66 adults in one tuberculosis unit in Bengaluru, so its findings cannot represent all TB patients in India. But the high percentage of participants who reported symptoms of anxiety and depression suggest that there is need for better integration of mental health screening into TB treatment.The researchers recommended routine screening for depression and anxiety when patients are diagnosed with TB and during follow-up visits. They also called for counselling and referrals for patients with more severe symptoms.They say that identifying psychological distress early may help doctors connect patients with appropriate support while they receive treatment for the infection. TB Is A Global Health CrisisEven though this study is based on a small sample, it speaks about the long-term effects of the disease on mental health. TB is a global health crisis, which means this study warrants further investigation and action. According to the WHO’s Global Tuberculosis Report 2025, in 2024, more than ten million people across the globe developed TB while more than 1.2 million lost their lives to the disease. Currently, India bears the lion's share of TB burden compared to other countries. Uneven access to drug-resistant TB treatment, financial hardships, stigma, prolonged treatment are some of the factors that may contribute to deteriorating mental health of TB patients.
