Summary
This study presents a rare case of hypnic headache potentially linked to basilar artery dolichoectasia. Verapamil treatment showed effectiveness in managing this unusual headache presentation.
Area of Science:
- Neurology
- Vascular Neurology
Background:
- Hypnic headache is typically classified as a primary headache disorder.
- However, secondary causes involving the pituitary, brainstem, or posterior fossa have been occasionally reported.
Observation:
- A 69-year-old woman presented with International Classification of Headache Disorders-II criteria-fulfilling hypnic headache over two years.
- Magnetic resonance imaging and angiography revealed basilar artery dolichoectasia.
Findings:
- This is the first reported case of hypnic headache associated with basilar artery dolichoectasia.
- The patient responded well to verapamil treatment.
Implications:
- The potential relationship between hypnic headache and basilar artery dolichoectasia warrants further investigation.
- This case expands the differential diagnosis for secondary hypnic headache.

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...

Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.

01:15Equilibrium and Balance
8.0K
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...

Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...

01:10The Arch of Aorta
2.2K
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

01:19Veins of Head and Neck
7.0K
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...
