The full name of pppd is persistent postural-perceptual dizziness, which is a multidisciplinary disease involving neurology, otolaryngology, and psychiatry, and is one of the common clinical diseases that cause patients to experience chronic dizziness. Persistent postural-perceptual dizziness is a multidisciplinary disease involving neurology, otolaryngology, and psychiatry, and it occurs in people with neurotic and introverted personalities, and is often accompanied by vestibular migraines, which can be triggered by complex visual stimuli and body movements. Patients with persistent postural-perceptual dizziness often experience dizziness for more than 3 months, lasting more than 15 days per month, which can be exacerbated by entering crowded and noisy places such as shopping malls and supermarkets, and relieved by lying down and resting. The disease should be treated by creating a quiet and comfortable environment for the patient as much as possible, and can also be treated with drugs such as fluoxetine hydrochloride and sertraline hydrochloride. If the diagnosis of persistent postural-perceptual dizziness is confirmed, please follow the doctor’s instructions for treatment, and do not use medication arbitrarily on your own.
