Neural Networks relevant to Psychiatric Disorders
Large scale brain networks refer to the complex and interconnected structures of the brain that involve multiple regions working in coordination. Advances in neuroimaging (such as fMRI, EEG, and MEG) and computational neuroscience have helped map these large-scale brain networks. Commonly discussed networks include - Default Mode Network (DMN), Salience Network (SN), Central Executive Network (CEN), Visual and Auditory Networks and many others.
Neurotransmitters in OCD
Obsessive-Compulsive Disorder (OCD) is a psychiatric condition characterized by the presence of obsessions (intrusive, unwanted thoughts, images, or urges) and compulsions (repetitive behaviors or mental acts performed to reduce anxiety associated with the obsessions). The underlying neurobiology of OCD is complex, but research points to abnormalities in neurotransmitter systems among many other factors. These neurotransmitters play a key role in regulating mood, cognition, anxiety, and motor behavior—areas directly impacted by OCD symptoms. Common neurotransmitters involved are - Serotonin (5HT), Dopamine, and Glutamate among others.
Sleep Hygiene
Sleep hygiene refers to a set of practices and habits essential for promoting good quality sleep. It involves creating an environment conducive to sleep and adopting daily routines that support consistent, restful nights. This includes maintaining a regular sleep schedule, even on weekends, and ensuring your bedroom is dark, quiet, and cool. Avoiding caffeine and heavy meals close to bedtime, limiting daytime naps, and incorporating a relaxing pre-sleep routine are also crucial. Poor sleep hygiene can lead to insomnia, fatigue, and impaired cognitive function. Prioritizing these practices significantly enhances overall health and well-being.
