Phrenasthenia, also known as neurasthenia, is a psychological disorder characterized by fatigue, headaches, sleep disturbances, difficulty concentrating, and other symptoms. It was first described in the late 19th century and is thought to be caused by an overload of stress or emotional responses to stimuli. Although it is no longer recognized as an official diagnosis, it is still widely accepted as an important mental health disorder that affects many individuals. Individuals with phrenasthenia often experience extreme fatigue and exhaustion even after getting plenty of sleep. They may also feel irritable, overwhelmed, and withdrawn. Cognitive problems, including difficulty concentrating, are also common. Other potential symptoms include anxiety, restlessness, dizziness, palpitations, headaches, and depression. Treatment for phrenasthenia typically involves a combination of cognitive behavioral therapy (CBT), lifestyle changes, and medications. CBT helps to adjust an individual’s thoughts and beliefs in order to reduce symptoms. Lifestyle changes such as regular exercise, restful sleep, mindful relaxation, and healthy dietary habits can also be helpful. In some cases, medications may be prescribed to help manage the symptoms and reduce stress. It is important to note that, due to the lack of research on phrenasthenia, there is no established treatment protocol for this disorder. If you have been diagnosed with phrenasthenia, it is best to speak with your doctor about different treatment options as well as possible lifestyle changes that could help you manage your condition.
