Persistent Postural Perceptual Dizziness In The Neurology Clinic
Irish Medical Journal
|October 8, 2024
Summary
Persistent Postural-Perceptual Dizziness (PPPD) affects 11% of neurology referrals for dizziness. Treatments like venlafaxine and vestibular physiotherapy show significant patient-perceived benefits for this condition.
Area of Science:
- Neurology
- Otolaryngology
- Vestibular Disorders
Background:
- Persistent Postural-Perceptual Dizziness (PPPD) is a common cause of chronic dizziness.
- Accurate diagnosis and effective treatment of PPPD are crucial for improving patient quality of life.
Purpose of the Study:
- To determine the proportion of new patient referrals to a General Neurology Clinic meeting PPPD diagnostic criteria.
- To evaluate patient-perceived treatment responses for PPPD.
Main Methods:
- Screened 1315 referral letters for dizziness, vertigo, or unsteadiness (2021-2023).
- Conducted a chart review to identify patients meeting PPPD criteria and assess treatment outcomes.
Main Results:
- 15.4% of referrals (202 patients) presented with dizziness-related symptoms; 11% (22 patients) met PPPD criteria.
- Venlafaxine improved symptoms by ≥50% in 80% of patients.
- Vestibular physiotherapy achieved ≥25% symptom improvement in 100% of patients.
Conclusions:
- PPPD is an under-recognized condition among neurology referrals for dizziness.
- Pharmacological (venlafaxine) and rehabilitative (vestibular physiotherapy) interventions show promise in managing PPPD symptoms.

01:15Equilibrium and Balance
4.5K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

01:29The Vestibular System
39.4K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

01:28Major Somatic Sensory Pathways
916
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
