Post-concussion – KnowNeuropsychology

These learning questions are brought to you by the KnowNeuropsychology / APPCN collaboration.

*This quiz has four multiple-choice questions.

1 / 4

A concussion, or mild traumatic brain injury, is a pathophysiological process affecting the brain, in which neurometabolic dysfunction underlies acute symptoms. What happens on a cellular level when a neurometabolic cascade occurs?

Potassium ions (K+) rush into the cell, while Calcium ions (CA2+) rushes out of the cell

Calcium ions (CA2+) rush into the cell, while Sodium ions (Na+) rush out of the cell

Calcium ions (CA2+) rush into the cell, while Potassium ions (K+) rush out of the cell.

Sodium ions (Na+) rush into the cell, while Potassium ions (K+) rush out of the cell

2 / 4

An expected time frame of clinical recovery of symptoms in adults following an uncomplicated sports-related concussion (SRC) is_______, but may take longer depending on pre-existing factors.

2-3 days

10-14 days

14-28 days

2-3 months

3 / 4

Some people experience visual disturbance following a concussion. When a person experiences disturbances in their ability to maintain binocular fixation, it is referred to as:

Convergence insufficiency

Saccadic dysfunction

Visual field deficit

Delayed visual processing

4 / 4

If a person continues to experience symptoms for more than three months following an uncomplicated concussion (or mild traumatic brain injury, mTBI), the symptoms are likely due to:

An ongoing neurometabolic cascade

Structural damage to the brain

Factors other than mTBI

Intracranial pressure
