My father (86) has dementia since the last 2 years and memory loss is increasing day by day. Please recommend some effective medicines.  — Rajesh Bagga, Dasuya, PunjabAround 25-30 pc people above 80 develop dementia, mostly Vascular or Alzheimer’s type. However, since dementia can be of many types, it is important to meet your general practitioner or neurologist to identify the type, as treatment varies for different types. Treatment can delay the course but usually dementia is a progressive illness. Early recognition is important. Prevention is more effective so encourage a routine that includes physical activity, socialisation and cognitive stimulation through new hobbies, puzzles, etc. — Dr Simmi Waraich, Psychiatrist, ChandigarhI have a history of borderline hypothyroidism. For the past few months, I am experiencing palpitations and anxiety before my periods. However, this has usually been limited as a PMS symptom only. What can be the underlying causes and precautions that I can take?  — Vaishali Gupta (26), KarsogPalpitations and anxiety before periods are commonly linked to hormonal changes seen in PMS, which can influence mood and heart rate. If you have borderline hypothyroidism, you may be more sensitive to these fluctuations. Regularly monitoring thyroid levels is important. Lifestyle measures such as good sleep, limiting caffeine, a balanced diet with magnesium-rich foods, light exercise, and relaxation techniques can help. If you experience extreme anxiety, consider psychotherapy and counselling. If symptoms are severe or occur outside your cycle, consult a doctor. — Dr Ritambhara Bhalla, Gynaecologist, Cloudnine Hospital, ChandigarhWhat should a person do to ensure that their body remains agile and healthy, their intellect sharp, and their mind calm, even in old age?  — Shakti Singh (39), KarnalOverall well-being comes from balance. Everyone should prioritise regular physical activity, a nutritious diet, and adequate sleep to keep the body agile. Continuous learning and meaningful conversations can keep the intellect sharp. To maintain a good mental health, practice mindfulness, manage stress, and nurture supportive relationships. For women, aligning activities with the menstrual cycle helps. They should use post-menstrual phase for new initiatives and intense workouts, and the premenstrual phase to slow down and rest. — Dr Monica Agarwal, Gynaecologist, Chandigarh
