Mood Swings: Understanding the science of the Rollercoaster

Dr. Porrselvi A.P., Founder, Clinical Lead, Cognitive Neuropsychologist, Unified Brain Health Care



Mood swings, those unpredictable emotional roller coasters, can significantly impact our everyday lives. Characterized by rapid shifts in emotions, from euphoria to despair, they can be both perplexing and distressing. Let's delve into some common culprits behind these fluctuations.   


Hormonal imbalances are frequently linked to mood swings. For women, hormonal changes associated with menstruation (PMS), pregnancy, and menopause can trigger these emotional ups and downs. Fluctuations in estrogen and progesterone levels can affect mood regulation, leading to irritability, sadness, or anxiety.   


Stress is another major contributor to mood swings. Whether it's a demanding job, relationship problems, or significant life changes, chronic stress can overwhelm our bodies, leading to emotional instability. When we feel overwhelmed or cornered, our bodies release stress hormones, which can disrupt mood.   


Neurological conditions can also play a role. ADHD, for example, is often associated with impulsivity and mood swings. One of the first symptoms of dementia can manifest as extreme mood fluctuations.   


Metabolic disorders, particularly those affecting the thyroid, can impact mood. An underactive thyroid (hypothyroidism) can lead to fatigue, depression, and mood swings. Conversely, an overactive thyroid (hyperthyroidism) can cause anxiety, irritability, and mood instability.   


Lifestyle factors also contribute to mood swings. Inadequate sleep, excessive caffeine or sugar consumption, and a sedentary lifestyle can disrupt our bodies' natural rhythms, leading to emotional imbalances. Excessive screen time and exposure to negative news can also contribute to mood swings by increasing stress and anxiety.   


In some cases, underlying psychological conditions, like mood or personality disorders, might be the root cause. Focused counselling and psychotherapy can help diagnose, understand and treat these conditions.


It's important to recognize that occasional mood swings are normal. However, if these fluctuations become persistent or significantly impact your daily life, it's essential to seek professional help. A healthcare provider can evaluate your symptoms and determine the underlying cause, offering appropriate treatment or management strategies.   


By understanding the potential causes of mood swings, you can take steps to manage them more effectively. Whether it's through stress management techniques, dietary adjustments, or seeking professional support, regaining control over your emotions is possible.
