- - - - - **Neurological Examination: Comprehensive Guide** ================================================= **Overview of Neurological Exam** --------------------------------- The neurological examination is a fundamental process for diagnosing and managing disorders affecting the nervous system. The exam focuses on localizing lesions, identifying signs of normal and abnormal neurological function, and guiding diagnostic and management decisions. **Key Objectives** ------------------ 1. - - 2. 3. - - - **Goals of the Neurological History** ------------------------------------- - - - Review of History: PRESENT ILLNESS - - - - - PMH: - - - - - - - **Indications for Neurological Examination** -------------------------------------------- - - - **Components of the Neurological Exam** --------------------------------------- ### 1.

Headache article The article is a comprehensive review of the diagnosis and management of headache disorders. It discusses the prevalence and classification of headache types, which are divided into primary and secondary headaches. Primary headache disorders include migraines, tension-type headaches (TTH), trigeminal autonomic cephalalgias (TACs), and other less common types. Secondary headaches are attributed to underlying medical conditions like vascular, infectious, or neoplastic causes. Key Points: 1\. Primary Headaches: Migraine is the most disabling and prevalent primary headache disorder, affecting 12% of people. It is treated with NSAIDs, triptans, gepants, and the newer 5-HT1F agonist lasmiditan. Tension-type Headache (TTH) affects 38% of the population and is managed with simple analgesics like acetaminophen and NSAIDs. Trigeminal Autonomic Cephalalgias (TACs), including cluster headaches, are rarer and present with unilateral pain and autonomic symptoms. 2\. Secondary Headaches: Secondary headaches are due to underlying issues and must be evaluated for possible urgent conditions such as cerebrovascular events or infections. 3\. Management: Acute treatment options include over-the-counter analgesics, triptans, and newer agents like gepants. Preventive treatments for migraines include antihypertensives, antidepressants, antiepileptics, botulinum toxin, and monoclonal antibodies targeting the calcitonin gene--related peptide (CGRP). 4\. Diagnostic Approach: Diagnosing headaches involves a thorough history and examination, focusing on distinguishing between primary and secondary causes. Diagnostic imaging or lumbar puncture is recommended in certain high-risk cases. 5\. Emerging Therapies: Neuromodulation devices and behavioral therapies are becoming increasingly recommended, particularly for patients with contraindications or who prefer nonpharmacological treatments.
