Increased Intracranial Pressure l: Introduction01:14

Increased Intracranial Pressure l: Introduction

27
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component...

Muscles that Move the Head01:19

Muscles that Move the Head

7.6K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

20
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

Arteries of the Head and Neck01:26

Arteries of the Head and Neck

4.3K
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Seizures l: Introduction01:20

Seizures l: Introduction

42
Understanding seizures and epilepsy relies on key definitions that help in recognizing, classifying, and managing these disorders. These definitions provide a framework for recognizing, classifying, and managing seizure disorders.DefinitionsA seizure is a sudden, abnormal burst of electrical activity in the brain that can cause changes in awareness, movement, sensation, or behavior, depending on the area involved. Epilepsy is a chronic condition characterized by recurrent, unprovoked seizures,...

Hepatic Encephalopathy01:29

Hepatic Encephalopathy

53
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic...

Area of Science:

  • Neurology
  • Chronobiology

Context:

  • Primary headache disorders, including migraine, cluster headache, and hypnic headache, are influenced by circadian rhythms.
  • Sleep disturbances (excess or lack) are known triggers for migraine attacks.
  • Cluster headache exhibits distinct chronological patterns and seasonal variations in attack frequency.

Purpose:

  • To explore the role of circadian rhythm and biological clock mechanisms in the pathophysiology of primary headache disorders.
  • To investigate the association between sleep patterns, hormonal factors (melatonin), genetic predispositions (orexin receptor 2 gene), and headache occurrence.
  • To examine neuroanatomical findings, particularly hypothalamic abnormalities, in relation to headache disorders and diurnal rhythm disturbances.

Summary:

  • Circadian rhythm disturbances are implicated in primary headache disorders, with specific patterns observed in migraine and cluster headache.
  • Hypothalamic abnormalities and reduced melatonin levels are noted in cluster headache, while orexin receptor 2 gene polymorphism is a risk factor.
  • Hypnic headache, also known as 'alarm clock headache,' shows a strict chronological pattern, and hypothalamic abnormalities have been detected.

Impact:

  • Highlights the critical role of the biological clock in headache pathophysiology.
  • Suggests potential therapeutic targets related to melatonin and orexin signaling for headache management.
  • Reinforces the importance of diurnal rhythm regulation in preventing and treating primary headache disorders.
