Veins of Head and Neck01:19

Veins of Head and Neck

1.5K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Arteries of the Head and Neck01:26

Arteries of the Head and Neck

1.1K
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...

Equilibrium and Balance01:15

Equilibrium and Balance

4.4K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Cranial and Spinal Meninges01:19

Cranial and Spinal Meninges

1.3K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Anxiety: Overview01:18

Anxiety: Overview

248
Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.

Insomnia01:27

Insomnia

79
Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.

Area of Science:

  • Neurology
  • Ophthalmology

Background:

  • Migraine with aura can cause transient visual disturbances.
  • Persistent visual changes after migraine with aura are uncommon.

Purpose of the Study:

  • To report a rare case of migrainous infarction.
  • To highlight persistent visual changes as a potential complication of migraine with aura.

Main Methods:

  • Case report of a 40-year-old male with persistent blurry vision.
  • Diagnostic workup included Humphrey visual field, CT head, and MRI brain.
  • Cardiology workup identified a patent foramen ovale.

Main Results:

  • Patient presented with persistent blurry vision in the right eye after a migraine with aura.
  • Imaging confirmed acute ischemia and infarct in the left occipital lobe.
  • Patent foramen ovale was identified as a potential contributing factor.

Conclusions:

  • Migrainous infarction should be considered in patients with persistent visual changes post-migraine with aura.
  • Early diagnosis and management are crucial for this rare neurological event.
