Summary
This case highlights a rare stroke presentation of hemichorea, emphasizing the limitations of the National Institutes of Health Stroke Scale (NIHSS) in guiding acute ischemic stroke treatment decisions.
Area of Science:
- Neurology
- Neuroscience
- Stroke Medicine
Background:
- Hyperkinetic movement disorders, such as hemichorea, are uncommon stroke manifestations.
- Typically, basal ganglia lesions are implicated, but insular cortex involvement is also documented.
Observation:
- A 78-year-old woman presented with acute transient dysarthria and left-sided chorea-like movements.
- Initial National Institutes of Health Stroke Scale (NIHSS) score was 0, with CT perfusion showing right M2 occlusion and MRI revealing an insular ischemic lesion.
Findings:
- Intravenous thrombolysis with alteplase was administered despite the low NIHSS score.
- Post-thrombolysis, the patient's hyperkinetic movements resolved completely.
- Follow-up MRI confirmed a confined insular ischemic lesion without basal ganglia involvement.
Implications:
- This case demonstrates the importance of clinical correlation and neuroimaging in stroke treatment decisions, even with low NIHSS scores.
- It underscores the limitations of the NIHSS in capturing the full clinical picture, particularly in cases involving movement disorders.
- Early thrombolysis can be effective in resolving stroke-induced hyperkinetic movement disorders.

01:28Muscles of the Leg that Move the Foot and Toes
1.6K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....

Loose connective tissue is found between many organs. Its main function is to absorb shock and bind tissues together. It also allows water, salts, and various nutrients to diffuse into cells that are embedded in it or present in adjacent tissues.
Adipose Tissue
Adipose tissue consists primarily of fat storage cells called adipocytes and little extracellular matrix. A large number of capillaries present within adipose tissue allow rapid mobilization of lipid molecules. White adipose tissue is...

00:58Introduction to Joints
3.0K
The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no...

01:18Static Friction
779
Static friction is a force that opposes the relative motion or tendency of motion between two surfaces in contact. It plays a crucial role in our daily lives, from walking on the ground to driving a car.
For example, consider a scenario where a truck is connected to a car by a rope, ready to tow it along a road. When no external force is applied by the truck, the car remains stationary and is said to be in static equilibrium. In this case, the forces acting on the car, such as gravity and the...

01:26Kinetic Friction
935
Consider a truck trying to pull a stationary car. As the truck exerts a force on the car, static friction is created at the point of contact between the two surfaces. This frictional force resists the car's movement and keeps it at rest. However, when the applied force by the truck surpasses the limiting static frictional force, an interesting phenomenon occurs. The frictional force at the interface reduces to a lower value, known as the kinetic frictional force. At this point, the car...

01:09Rolling Without Slipping
3.7K
People have observed the rolling motion without slipping ever since the invention of the wheel. For example, one can look at the interaction between a car's tires and the surface of the road. If the driver presses the accelerator to the floor so that the tires spin without the car moving forward, there must be kinetic friction between the wheels and the road's surface. If the driver slowly presses the accelerator, causing the car to move forward, the tires roll without slipping. It is...
