    Neurology® Clinical Practice The evaluation of a patient with dizziness Kevin A. Kerber, MD Robert W. Baloh, MD Summary Dizziness is the quintessential symptom presenta- tion in all of clinical medicine. It can stem from a disturbance in nearly any system of the body. Pa- tient descriptions of the symptom are often vague and inconsistent, so careful probing is essential. The physical examination is performed by observ- ing the patient at rest and following simple move- ments or bedside tests. In general, no special tools are required. The causes of dizziness range from benign to life-threatening disorders, and features that distinguish among these may be subtle. When diagnostic testing is considered, parsimony should be the rule. Identifying common peripheral vestibu- lar disorders is a priority. Picking this “low hanging fruit” can be the key component to excluding more serious central causes of dizziness. eurologists play an important role in the evaluation and management of pa- tients with dizziness. The possibility of a serious neurologic disorder is un- Nnerving to front-line physicians who have ranked decision support for identifying central causes of vertigo as a top priority.1 Although dangerous cen- tral disorders do not commonly present as isolated dizziness, stroke and other neurologic disorders can occur in this manner. The history and physical examination are the critical elements in determining the management of these patients. In this article, we review the approach to the evaluation and management of patients with dizziness. History The first step in assessing a patient presenting with dizziness is to define the symptom (table 1).

  • Second Edition
    COVID-19 Evidence Update COVID-19 Update from SAHMRI, Health Translation SA and the Commission on Excellence and Innovation in Health Updated 4 May 2020 – 2nd Edition “What is the prevalence, positive predictive value, negative predictive value, sensitivity and specificity of anosmia in the diagnosis of COVID-19?” Executive Summary There is widespread reporting of a potential link between anosmia (loss of smell) and ageusia (loss of taste) and SARS-COV-2 infection, as an early sign and with sudden onset predominantly without nasal obstruction. There are calls for anosmia and ageusia to be recognised as symptoms for COVID-19. Since the 1st edition of this briefing (25 March 2020), there has been a significant expansion of literature on this topic, including 3 systematic reviews. Predictive value: The reported prevalence of anosmia/hyposmia and ageusia/hypogeusia in SARS-COV-2 positive patients are in the order of 36-68% and 33-71% respectively. There are reports of anosmia as the first symptom in some patients. Estimates from one study for hyposmia and hypogeusia: • Positive likelihood ratios: 4.5 and 5.8 • Sensitivity: 46% and 62% • Specificity: 90% and 89% The US Centres for Disease Control and Prevention (CDC) has added new loss or taste or smell to its list of recognised symptoms for SARS-COV-2 infection. To date, the World Health Organization has not. Conclusion: There is sufficient evidence to warrant adding loss of taste and smell to the list of symptoms for COVID-19 and promoting this information to the public. Context • Early detection of COVID-19 is key to the ongoing management of the pandemic.

  • Dizziness Related to Anxiety and Stress
    Dizziness Related to Anxiety and Stress Author: Laura O. Morris, PT, NCS Fact Sheet Why does anxiety and stress cause me to be dizzy? Dizziness is a common symptom of anxiety stress and, and If one is experiencing anxiety, dizziness can result. On the other hand, dizziness can be anxiety producing. The vestibular system is responsible for sensing body position and movement in our surroundings. The vestibular system is made up of an inner ear on each side, specific areas of the brain, and the nerves that connect them. This system is responsible for the sense of dizziness when things go wrong. Scientists believe that the areas in the brain responsible for dizziness interact with the areas responsible for anxiety, and cause both symptoms. Produced by The dizziness that accompanies anxiety is often described as a sense of lightheadedness or wooziness. There may be a feeling of motion or spinning inside rather than in the environment. Sometimes there is a sense of swaying even though you are standing still. Environments like grocery stores, crowded malls or wide-open spaces may cause a sense of imbalance and disequilibrium. These symptoms are caused by legitimate physiologic changes within the brain. A Special Interest Group of If there is an abnormality in the vestibular system, the symptom of dizziness can be the result. If one already has a tendency toward anxiety, dizziness from the vestibular system and anxiety can interact, making symptoms worse. Often the anxiety and the dizziness must be treated together in order for improvement to be made. How does physical therapy help?

  • Neuropsychiatric Manifestations of COVID-19 Can Be Clustered in Three
    www.nature.com/scientificreports OPEN Neuropsychiatric manifestations of COVID‑19 can be clustered in three distinct symptom categories Fatemeh Sadat Mirfazeli1,8, Atiye Sarabi‑Jamab2,8, Amin Jahanbakhshi3, Alireza Kordi4, Parisa Javadnia4, Seyed Vahid Shariat1, Oldooz Aloosh5, Mostafa Almasi‑Dooghaee6 & Seyed Hamid Reza Faiz7* Several studies have reported clinical manifestations of the new coronavirus disease. However, few studies have systematically evaluated the neuropsychiatric complications of COVID‑19. We reviewed the medical records of 201 patients with confrmed COVID‑19 (52 outpatients and 149 inpatients) that were treated in a large referral center in Tehran, Iran from March 2019 to May 2020. We used clustering approach to categorize clinical symptoms. One hundred and ffty‑one patients showed at least one neuropsychiatric symptom. Limb force reductions, headache followed by anosmia, hypogeusia were among the most common neuropsychiatric symptoms in COVID‑19 patients. Hierarchical clustering analysis showed that neuropsychiatric symptoms group together in three distinct groups: anosmia and hypogeusia; dizziness, headache, and limb force reduction; photophobia, mental state change, hallucination, vision and speech problem, seizure, stroke, and balance disturbance. Three non‑ neuropsychiatric cluster of symptoms included diarrhea and nausea; cough and dyspnea; and fever and weakness. Neuropsychiatric presentations are very prevalent and heterogeneous in patients with coronavirus 2 infection and these heterogeneous presentations may be originating from diferent underlying mechanisms. Anosmia and hypogeusia seem to be distinct from more general constitutional‑like and more specifc neuropsychiatric symptoms. Skeletal muscular manifestations might be a constitutional or a neuropsychiatric symptom. In December 2019 a number of severe acute respiratory syndrome (SARS) were reported in Wuhan, China that became eventually a pandemic infection with over 8 million reported cases until June 2020 1.
