Sleep disturbances are key predictors of mental health issues in adolescents: study
CHENNAI: Sleep disturbances are a significant predictor of future mental health issues in adolescents, confirms a latest study published in Nature Medicine.
The comprehensive study involving over 11,000 adolescents from the Adolescent Brain and Cognitive Development (ABCD) study revealed that sleep disturbances are a significant predictor of future mental health issues, including depression and anxiety.
The study, conducted by a team of senior medical scientists at Duke University School of Medicine, Durham, US, found that sleep problems were more predictive of mental health concerns than other known risk factors such as adverse childhood experiences and family history of mental illness.
Interestingly, brain imaging data (MRI scans) did not enhance the ability to predict mental health risks, suggesting that psychosocial factors like sleep disturbances may be more crucial indicators.
The study followed adolescents aged 9 to 15 years, with approximately 48% female participants, who underwent various assessments, including sleep quality evaluations and brain imaging.
The researchers used Machine Learning models developed to analyse the data and predict future mental health outcomes.
Implications for Mental Health
According to senior psychiatrists Dr Reji Philips, and consultant psychologist Ramon Srivastava, both from Mumbai, recognising sleep disturbances early can help identify adolescents at risk for developing mental health issues, allowing for timely interventions.
Addressing sleep problems in adolescents may serve as an effective strategy to prevent the onset of psychiatric disorders.
Implementing policies that promote healthy sleep habits among adolescents could be beneficial for public health, they say.
However, there were certain limitations in the study in establishing a direct cause and effect relationship sleep disorders with mental health clinically.
The study identifies associations between sleep disturbances and mental health issues but does not confirm a direct cause-and-effect relationship, the report says. Hence additional studies are needed to explore the underlying mechanisms and to develop effective interventions.
Mental health experts, however, agree that while addressing these sleep problems early on can play a crucial role in preventing the development of psychiatric disorders, it highlights the importance of promoting healthy sleep habits and considering sleep quality in mental health assessments.

Parrot with neurology issuegets MRI scan, acupuncture
Mumbai: A parrot was put through an MRI scan and is undergoing acupuncture for a neurological disorder. Found by a car-washer under a vehicle in Chembur, the bird has ataxia — a neurological problem — but is showing signs of slow recovery. When it was found under a car, the parrot kept trembling. It could not bend its neck to have water from a bowl nor could it bite into food. An x-ray did not show anything much, said Dr Deepa Katyal Engineer who is treating the bird. "It had a traumatic injury to the tail. The shaking of its body pointed to ataxia which could be a neurological issue," said the vet, who specialises in pain management with special interest in neurological disorders. For a conclusive diagnosis, an MRI scan of the brain and spine was done at a facility for humans. "We needed to first be sure if it was a neurological issue. If yes, whether or not it was reversible," said Dr Katyal. To get the bird under the MRI machine, it had to be administered anaesthesia. While doing an MRI scan, movement is not allowed, while this bird was constantly moving. "Images would not have been possible without anaesthesia," the vet said, adding that a respiratory tube was attached to the little bird as an airway access while using injectable anaesthesia. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Cardiologists: 1 Teaspoon of This Before Bed Melts Belly Fat Like Crazy Hollywood News | USA Click Here Undo The scan detected changes in the area of injury which pointed to lack of coordination between muscle and nerves. Also, the bird's tail bone, which has nerve endings, was affected. "The spinal nerve bundle also had inflammation," said Dr Katyal. The parrot is being administered painkillers, phototherapy and acupuncture. "Birds can't be over-medicated with drugs as blood flow to the liver and kidneys can get reduced, affecting their function long term," said the vet treating the bird at her clinic, Animal Wellness & Rehabilitation Centre, Chembur. The bird is being given acupuncture treatment thrice a week. Acupuncture helps strengthen the nerves, Dr Katyal said. It is also being treated daily with 'phototherapy', an advanced therapy in pain management which improves blood flow and reduces inflammation. It helps improve the affected part and helps regenerate new cells. In less than a week, the parrot started taking baby steps, and pecking at food, including being able to strip sunflower seeds. "It is walking slowly, but still staggers… Overall, it is showing improvement," said the doctor. "I hope its tail injury will regenerate into normal functioning soon, though such issues can take months."

Hope, precision and healing: advancing brain tumour care
A brain tumour is an abnormal mass or growth of cells in the brain. The sudden and unpredictable nature of brain tumours highlight how these conditions can affect individuals of any age, often without warning. These complex tumours range from benign growths to aggressive cancers. Increasing awareness about early symptoms and treatment options can dramatically improve clinical outcomes for patients, giving them a second chance at life. Stories of hope All patients with brain tumours have a unique story of how they faced their distinct set of challenges. Consider the story of Mr. G, a devoted father and businessman diagnosed with a right temporal glioblastoma. In an initial surgery, only the tumour's core was removed, and the cancer margins regrew to their original size before radiation could be started. An MRI scan revealed that another surgery was needed. With an intraoperative ultrasound and neuronavigation, our team at was able to remove the tumour completely and safely. Today, Mr. G is stable and recovering well. He will soon receive Proton Beam Therapy — a form of targeted radiation. Neuronavigation systems provide GPS-like precision inside the brain, while an intraoperative ultrasound helps locate the tumour in real time. Together, these tools have increased the extent of tumour removal — a factor closely tied to survival. Some tumours hide in the brain's deepest, most delicate regions. This was the case with 18-year-old K.S. from Ethiopia, who first underwent surgery and radiation for a brain tumour in 2019. When he returned to India in early 2024 with one-sided weakness, imaging revealed a cystic lesion with a calcified component deep within the midbrain. Pathology confirmed it as a benign pilocytic astrocytoma. After draining the cyst, there was some improvement but symptoms recurred a year later. Facing a recurrence in a high-risk location, an ultrasonic aspirator and meticulous microsurgical techniques were used to remove the lesion entirely. Now tumour-free, K.S. has returned home with a restored future. In hard-to-reach brain areas that control speech, movement, and vision, ultrasonic surgical aspirators are vital. At 19, Mr. E experienced sudden seizures and foot paralysis. Scans revealed a 3 cm tumour situated in the right motor cortex, the area that controls voluntary movement. Preserving function in such delicate terrain is paramount. Surgeons used real-time neurophysiological monitoring with neuro-navigation and an intraoperative ultrasound to map critical brain regions and guide the resection. A tiny residual margin, deemed too risky for surgical removal, was scheduled for precision proton therapy. Neurophysiological monitoring tracks brain function during surgery, helping surgeons avoid damage to critical areas and preserve key abilities like movement and speech. Modern advances in medical technology Brain tumour care has evolved dramatically since the days of basic imaging and single-angle X-rays. Modern neuro-navigation systems function like an internal GPS, while intraoperative ultrasounds provide live visualisation of tumour boundaries. Ultrasonic aspirators rapidly break up tumour tissue with sound waves, enabling gentle suction and irrigation that shorten the duration of surgery. In radiation therapy, proton beam treatment delivers radiation layer by layer, conforming tightly to the tumour, sparing surrounding tissues and reducing side effects by up to 60%, particularly in children. For patients who cannot undergo surgery or have deep-seated lesions, gyroscopic radiosurgery platforms offer fully non-invasive, outpatient treatments in sessions as brief as 30 minutes, targeting tumours from multiple angles with surgical precision. No single specialty works in isolation. Each individual with a brain tumour diagnosis benefits from a multidisciplinary tumour board - neurosurgeons, medical and radiation oncologists, imaging specialists, pathologists, geneticists, and rehabilitation therapists collaborate on every diagnosis and treatment plan. Advanced technology and compassionate care go hand in hand, ensuring every patient feels informed and supported throughout their journey. The power of early action Brain tumours can be unpredictable: some remain stable for years, while others can double in size within weeks. Persistent headaches, sudden vision changes, seizures, memory lapses, or unexplained limb weakness should never be overlooked. Timely MRI or CT scans can open the door to more treatment options and better outcomes. As cutting-edge technology continues to develop and care teams refine their expertise, the message is one of optimism that even in the most complex cases, there remains hope for healing. By turning early warnings into prompt action, patients can look forward to the brightest possible tomorrow with a chance at a new life! (Dr. Ari G.

International Yoga Day 2025: Can this ancient practice really improve your mental well-being? Experts answer
In today's fast-paced world, mental well-being is just as important as our physical health, and yoga can bridge the gap between the two. More than just a fitness trend, doctors and mental health experts now recognise yoga as a powerful tool to help manage anxiety and depression and boost emotional balance. On International Yoga Day 2025, let's understand how yoga helps improve mental health. According to a Harvard Health Publishing report, research using MRI and other brain imaging tools has found that regular yoga practitioners tend to have a thicker cerebral cortex—responsible for processing information—and a larger hippocampus, which plays a key role in learning and memory. Yoga helps to provide a powerful and holistic approach to improving mental health. "It helps to sync the mind and body and regulate the stress response system, lower cortisol levels, and promote the release of mood-enhancing chemicals like serotonin and dopamine," says Dr Santosh Bangar, Senior Consultant Psychiatrist, Gleneagles Hospitals Parel, Mumbai. Yoga for mental health: Does it really work? Regular yoga can help with anxiety, depression, and stress. The mindfulness and breathing techniques taught in yoga help calm the mind and promote a sense of inner peace. Over time, yoga enhances self-awareness and supports better sleep, improves focus, and helps with a balanced mood. "For people dealing with trauma, burnout, or day-to-day emotional fatigue, yoga can be a boon. It can help you relax and rejuvenate," adds Dr. Bangar. Credit: Pexels Yoga is not only about flexibility and balance but also about de-stressing and giving peace of mind. It is a good idea to do yoga for 45 minutes a day and see a meaningful difference. Ensure to do it under the guidance of a certified practitioner. Yoga is extremely effective for long-term health and wellness. According to Vidya Jha, yoga guru at Aatma Yog Studio, Karampura, New Delhi, "Yoga helps calm the nervous system through mindful movement and controlled breathing (pranayama), which can lower cortisol levels (the stress hormone)." Alleviates Anxiety and Depression: Regular practice has been shown to activate the parasympathetic nervous system, promoting relaxation. It also boosts levels of serotonin and gamma-aminobutyric acid (GABA), which are associated with improved mood.
