Unarousable Unresponsiveness in Which the Patient Lies with the Eye Closed and Has No Awareness of Self and Surroundings (2)
Neurological Disease Deborah M Stein, MD, MPH 1. Coma a. Coma is defined as “a state of extreme unresponsiveness, in which an individual exhibits no voluntary movement or behavior” (1). i. Alternatively, coma is a state of unarousable unresponsiveness in which the patient lies with the eye closed and has no awareness of self and surroundings (2). b. Coma lies on a spectrum with other alterations in consciousness – from confusion to delirium to obtundation to stupor to coma and, ultimately, brain death (2). c. To be clearly distinguished from syncope, concussion, or other states of transient unconsciousness coma must persist for at least one hour (2). d. There are 2 important characteristics of the conscious state (3) i. The level of consciousness – “arousal or wakefulness” 1. Regulated by physiological functioning and consists of more primitive responsiveness to the world such as predictable involuntary reflex responses to stimuli. 2. Arousal is maintained by the reticular activating system (RAS) - a network of structures (including the brainstem, the medulla, and the thalamus) ii. The content of consciousness – “awareness” 1. Regulated by cortical areas within the cerebral hemispheres, e. There are two main causes for coma: i. Bihemispheric diffuse cortical or white matter damage or ii. Brainstem lesions bilaterally affecting the subcortical reticular activating systems. f. A huge number of conditions can result in coma. One way to categorize these conditions is to divide them into the anatomic and the metabolic causes of coma. i. Anatomic causes of coma are those conditions that disrupt the normal physical architecture and anatomy, either at the level of the cerebral cortex or the brainstem ii. -

Neurologic Manifestations of Hypoglycemia
13 Neurologic Manifestations of Hypoglycemia William P. Neil and Thomas M. Hemmen University of California, San Diego United States of America (USA) 1. Introduction Unlike most other body tissues, the brain requires a continuous supply of glucose. It has very limited endogenous glycogen stores, and does not produce glucose intrinsically.1 Although it accounts for 2% of body weight, the brain utilizes 25% of the body’s glucose due to its high metabolic rate.2, 3 Evidence for the brains sole reliance on glucose came from obtaining a respiratory quotient of one after measuring differences between arterial and venous content of oxygen and carbon dioxide in blood traveling through the brain.4 In the past, neurons were thought to directly metabolize glucose, however, more recent studies suggest astrocytes may play an important role in glucose metabolism.5 Astrocytic foot processes surround brain capillaries, which deliver glucose to the brain. With this, they form the first cellular barrier for entering glucose.5 Astrocytes contain the non-insulin dependent GLUT1 transporter, as well as the insulin dependent GLUT4 transporter, suggesting a possible role for astrocytes in regulating and storing brain glucose in an insulin dependent and independent manner (see figure 1).6-8 In addition to glucose, the brain contains a very limited store of glycogen, (between 0.5 and 1.5 g, or about 0.1% of total brain weight). Unlike peripheral tissue, where glycogen is readily mobilized during hypoglycemia, the brain can only function normally for a limited duration. Glycogen content seems to fall in areas of highest brain metabolic rate, suggesting at least some, albeit limited role as fuel during hypoglycemia.7 Although the brain relies primarily on glucose during normal conditions, it can use ketone bodies during starvation. -

THE GENERAL PRINCIPLES OF HISTORY TAKING Irena Zakarija-Grković, MD, FRACGP, IBCLC, PhD A Brief Overview of Clinical Medicine From classical Greek times interrogation of the patient has been considered most important. However, the current emphasis on the use of history taking and physical examination for diagnosis developed only in the 19th century. Until the 19th century, diagnosis was empirical and based on the classical Greek beliefs that all disease had a single cause, an imbalance of the four humours or body fluids (yellow bile, black bile, blood and phlegm). In the 17th century physicians based their opinion on a history provided by an apothecary (assistant) and rarely saw the patients themselves. Thomas Sydenham (1624-1689) began to practise more modern bedside medicine basing his treatment on experience and not theory. A renaissance in clinical methods began with the concept of Battista Morgagni (1682-1771) that disease was not generalised but arose in organs, a conclusion published in 1761. Leopold Auenbrugger invented chest tapping (percussion) to detect disease in the same year. -
Postconcussional Disorder and Loss of Consciousness
Postconcussional Disorder and Loss of Consciousness Stephen D. Anderson, MD, FRCP(C) Postconcussional disorder (PCD) has been described in the psychiatric, neuro- logical, neuropsychological, and rehabilitation medicine literature for many years. PCD has recently been introduced into DSM-IV, appearing in an appendix that contains a number of proposals for new categories and axes that were suggested for possible inclusion in DSM-IV. There are some major difficulties with the proposed criteria for PCD. This article explores some of these difficulties, partic- ularly focusing on the criteria of loss of consciousness (LOC). A review of the literature demonstrates that LOC is not necessary for PCD to occur. The major difficulty with the DSM-IV criteria is the definition of concussion. The article suggests that, instead, the criteria for mild traumatic brain injury, as defined by the American Congress of Rehabilitation Medicine, may be more appropriate. Postconcussional disorder (PCD) has been symptoms include headache pain, nausea. described in the medical literature for dizziness or vertigo. unsteadiness or poor over a century.

Types of Brain Dysfunction in Critical Illness Robert D
Neurol Clin 26 (2008) 469–486 Types of Brain Dysfunction in Critical Illness Robert D. Stevens, MD*, Paul A. Nyquist, MD, MPH Departments of Anesthesiology Critical Care Medicine, Neurology, and Neurological Surgery, Johns Hopkins University School of Medicine, Meyer 8-140, 600 North Wolfe Street, Baltimore, MD 21287, USA Many patients in the ICU develop a global alteration in cognitive func- tion that may be structural or metabolic in origin [1]. Terms used to describe these disturbances include delirium, acute confusional state, organic brain syndrome, acute organic reaction, cerebral insufficiency, brain failure, ICU psychosis, and encephalopathy. Etiology-specific terms, such as septic encephalopathy or hepatic encephalopathy, have been used when there is a strong presumption regarding the causative mechanism. It has been pos- tulated that many of these disorders are clinical expressions of a pathophys- iologic spectrum, collectively referred to as ‘‘critical illness brain syndrome’’ [2], ‘‘critical illness–associated cognitive dysfunction’’ [3], or ‘‘critical illness encephalopathy’’ [1]. Recently, there has been an effort to rationalize this terminology and to classify brain dysfunction in the ICU as either delirium or coma, using validated clinical criteria [4–7]. Coma Clinical assessment In the clinical realm consciousness is described in terms of two primary neurologic functions: arousal or wakefulness, and awareness of self and of the environment [8]. Awareness is the content of consciousness and includes multiple cognitive domains including perception, attention, memory, This is an updated version of an article that originally appeared in Critical Care Clinics, volume 22, issue 4. * Corresponding author.
