ADVERTISEMENTS: In this article we will discuss about the Nerve Tissue:- 1. Inherited disorders of carbohydrate metabolism. If you have a Acquired or secondary derangements in carbohydrate metabolism, such as diabetic ketoacidosis, hyperosmolar coma, and hypoglycemia, all affect the central nervous system. Many forms and variants of peripheral nerve disease also are seen in diabetes. Metabolism is the process your body uses to make energy from the food you eat. In: Burman D, Holton J B, Pennock C A (eds). Start studying Chapter 10: Nervous system diseases and disorders-Thomas. They appear as white matter, because most mammalian axons have a white myelin sheath around them, which helps to speed up nerve conduction. It produces chemicals that either stimulate or suppress hormone secretions of the pituitary gland. Many systemic disorders with metabolic origin, like amyloidosis, hepatic failure, vitamin deficiencies, uremia, lipid metabolism disorders, and others, can also cause axonal or myelin alterations in the peripheral nervous system. According to a recent survey by the World Health Organisation, nearly 1-3% of the children in all the countries are suffering from metabolic disorders. Classification of the acquired metabolic disorders of the nervous system in adults Presenting as a syndrome of confusion, stupor or coma ischemia-hypoxia hypercapnia hypoglycemia hyperglycemia hepatic failure reye syndrome azotemia disturbance of sodium, water balance & osmolality acidosis … Bio217 Fall2012 Unit IV 1 Bio217: Pathophysiology Class Notes Professor Linda Falkow Unit IV: Nervous System Disorders Chap. This overview was designed primarily to provide examples of hereditary metabolic disorders that result in nervous system dysfunction. The prevalence of neuropathy ranges from 2% to 8%, with more than 20 million Americans estimated to be affected by the disease. Chemicals in your digestive system (enzymes) break the food parts down into sugars and acids, your body's fuel. A variety of pharmacologic, structural, and metabolic disorders of the CNS are characterized by depression of the neural drive to breathe. PPT, Notes. The field of inherited disorders of the nervous system has undergone major revolutions in the past 150 years. Most enzymopathies become manifest in infancy and childhood; only a few appear as late as adolescence or adult life. Baerlocher K, Gitzelmann R, Steinmann B (1980) Clinical and genetic studies of disorders in fructose metabolism. The consequent homeostatic disturbances produce a neurologic or developmental abnormality. These constitute only one-third of the known recessive (autosomal and X-linked) disorders. 5 Neurological Disorders - Neurological disorders are diseases of the central and peripheral nervous system. In other words, the brain, spinal cord, cranial nerves, peripheral nerves, nerve roots, autonomic nervous system, neuromuscular junction, and muscles. | PowerPoint PPT presentation | free to view Physicians should also suspect peripheral nervous system disorders in patients with generalized or diffuse weakness but no sensory deficits; in these cases, peripheral nervous system disorders may be overlooked because they are not the most likely cause of such symptoms. THE PERIPHERAL NERVOUS SYSTEM Peripheral nerves are just bundles of axons. These drugs importantly either promote or decrease the action of a particular Several drugs are used to change the mood and/or emotional state of the user. This chapter includes a review of the effects of accidental and deliberate exposure to industrial and environmental toxins and drugs of addiction including alcohol. Disorders of carbohydrate metabolism occur in many forms. Cholinergic and Adrenergic 8. Therapeutic approaches for the correction of such disorders are discussed … Food is made up of proteins, carbohydrates, and fats. Glial component, supportive Microglia, the police force of the CNS For example, the brain needs calcium, potassium, and sodium to generate electrical impulses, and lipids (fats and oils) to maintain a healthy nervous system. Nature of the Chemical Transmitters 7. Peripheral nerves consist of fascicles that contain myelinated and unmyelinated axons. Of all neuromuscular disorders, peripheral neuropathy, abbreviated here as neuropathy, is the most frequent. Metabolic disorders may affect people of all age groups and usually have adverse neurological and cardiovascular effects. The basic unit of the nervous system is the nerve cell (neuron). Toxic, nutritional and metabolic derangements can cause damage to the nervous system by a variety of mechanisms and lead to a wide spectrum of characteristic neurological disorders. The nervous system has two distinct parts: the central nervous system (the brain and spinal cord) and the peripheral nervous system (the nerves outside the brain and spinal cord). Metabolic neuropathies are nerve disorders that occur with diseases that disrupt the chemical processes in the body. Particular clinical presentations of neurometabolic disorders include ataxias, movement disorders, childhood epilepsies, or peripheral neuropathy. Detailed coverage of the entire range of inherited metabolic diseases of the nervous system is available in other texts (Brett 1997; Scriver et al. The nervous system is formed during the first month of embryonic development; therefore, any maternal infection can have extremely harmful effects Maternal measles (rubella) = deafness Lack of O 2 for minutes can cause neuron death Learn vocabulary, terms, and more with flashcards, games, and other study tools. Disorders of the Peripheral Nervous System Peripheral Nerve Disorders The spectrum of peripheral nerve disorders includes Mononeuropathies (entrapment, trauma, etc ... – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 7546a9-MjYxM Structure of a Typical Nerve 2.

Chemical Composition of the Nerve Tissue 3. ACQUIRED METABOLIC. Transmission of Nerve Impulse from One Neurone of Other 6. Nutritional deficiency can affect the structural, functional, and biochemical integrity of the nervous system in the same manner as it does the structural, functional, and biochemical integrity of the body’s other organ systems. Neurological disorders are the disorder of the brain and nervous system, and there are more than 600 kinds have been discovered. Your body can use this fuel right away, or it can store the energy in your body tissues. 13: Pain, Temperature, Sleep, and Sensory Chap. Path: Demyelinating Disorders & Metabolic Diseases of Nervous System study guide by smlorenzo includes 46 questions covering vocabulary, terms and more. Primary disorders of energy metabolism are those in which the primary insult affects the cellular machinery required for energy metabolism. The most common disorders are acquired. Endoneurium is the small amount of matrix that is present between individual axons. Approximately 45% of children present with neurologic signs [] (Table 2).Most patients with neuromuscular symptoms will have either normal or only slightly elevated (<2 × normal) serum creatine kinase [12–15].The results of electromyography and nerve conduction studies are also usually normal []. Inherited Metabolic Diseases of the Nervous System John H. Menkes William R. Wilcox The diseases considered in this chapter result from a single mutant gene that codes for an enzymatic protein that in most instances is involved in a catabolic pathway. MTP, Lancaster, pp 163–190 CrossRef Google Scholar Metabolic and Degenerative Diseases of the Central Nervous System is a comprehensive reference work that provides the neuroscience community with valuable, current, and scholarly summaries on every known degenerative disorder. Nerve Impulse 5. Various disorders result from genetically determined abnormalities of enzymes, the metabolic consequences of which affect the development or functioning of the nervous system. In all of these conditions, the main neuropathological and clinical abnormalities are described in terms of metabolic changes, which might, in different ways, influence the neuronal or glial cells and the neuroaxonal circuits as the nervous system cells have a selective vulnerability to the different biochemical dysfunctions. Some of the more frequently encountered pathological conditions were selected in order to illustrate the mechanisms and the consequences of the metabolic derangements. https://www.slideshare.net/AmrHasanNeuro/neurometabolic-disorders The nervous system is the most commonly affected system in mitochondrial disorders. Transmission of an Impulse from […] Quizlet flashcards, activities and games help you improve your grades. The separation between conditions… This term refers rather loosely to the pathways responsible for the utilization of the major substrates of brain. Many damage the nervous system so severely that survival to adult years and reproduction are impossible, and some cause death in utero. The hypothalamus is a collection of specialized cells located in the brain, and is the primary link between the two systems. PDF | On Jan 1, 2014, Vrajesh Udani and others published Metabolic Disorders of Nervous System | Find, read and cite all the research you need on ResearchGate "Energy metabolism" is deranged in a wide variety of disorders of the nervous system. Acquired or secondary derangements in carbohydrate metabolism, such as diabetic ketoacidosis, hyperosmolar coma, and hypoglycemia, all affect the central nervous system. This overview was designed primarily to provide examples of hereditary metabolic disorders that result in nervous system dysfunction. | PowerPoint PPT presentation | free to view Neurological Disorders - NEUROLOGICAL DISORDERS Dementia A degenerative syndrome characterized by deficits in memory, language, and mood. The 19th century saw the first systemic approach to disease through the use of rational, consistent outlines for taking histories and doing physical examinations. Metabolism 4. The hypothalamus modulates the activities of the anterior and posterior lobes of the pituitary in different ways. Metabolic Processes: Cushing Syndrome and Addison’s Disease As might be expected for a fundamental physiological process like metabolism, errors or malfunctions in metabolic processing lead to a pathophysiology or—if uncorrected—a disease state. An important segment of neurologic medicine, and one that is seen with great frequency in general hospitals, are disorders in which a global disturbance of cerebral function (encephalopathy) results from failure of some other organ system—heart and circulation, lungs and respiration, kidneys, liver, pancreas, and the endocrine glands. The endocrine system and nervous system work together to help maintain homeostasis… balance. Peripheral nervous system disorders contribute substantially to the burden of neurological disease. Metabolic disorders can … Neurohormones synthesized in the hypothalamus reach the anterior pituitary (adenohypophysis) through a specialized portal vascular system and regulate synthesis and release of the 6 major peptide hormones of the anterior pituitary (see figure The pituitary and its target organs). amyotrophic lateral sclerosis: A chronic, progressive disease characterized by degeneration of the central nervous system and the loss of voluntary muscle control.
