Persisting Symptoms after Concussion

Persisting Symptoms after Concussion (PSaC)
While post-concussion syndrome (PCS) is the term many people still use, the new term used by researchers and clinicians is persisting symptoms after concussion (PSaC). The reason for the change is that each person who sustains a concussion will have a different combination of symptoms. In contrast, “syndrome” means a group of symptoms that always occur together.

A Complete Guide to Post-Concussion Syndrome
Post-concussion syndrome, also known as persistent post-concussion symptoms (PPCS), occurs when concussion symptoms persist for months or years after you sustain a mild traumatic brain injury (mTBI) or another type of brain trauma.
A Multidimensional Approach to Post-concussion Symptoms in Mild Traumatic Brain Injury
Mild traumatic brain injury (mTBI) presents a substantial burden to patients, families, and health care systems. Whereas, recovery can be expected in the majority of patients, a subset continues to report persisting somatic, cognitive, emotional, and/or behavioral problems, generally referred to as post-concussion syndrome (PCS). However, this term has been the subject of debate since the mechanisms underlying post-concussion symptoms and the role of pre- and post-injury-related factors are still poorly understood.

Post-Concussion Syndrome and Chronic Traumatic Encephalopathy: Narrative Review on the Neuropathology, Neuroimaging and Fluid Biomarkers
Post-concussion syndrome (PCS) is a sequela of minor brain injury. Although about 29–90% of patients may experience PCS after a head injury, its etiology is unclear. Despite that no universally accepted definition of PCS exists, it is generally accepted as the development of at least three of the following symptoms: headache, fatigue, irritability, dizziness, and balance issues, affected sleep, poor memory and concentration, and increased sensitivity to light and noise

Complete Concussions
Prolonged Concussion Symptoms, formerly known as Post-Concussion Syndrome (PCS), create a complex clinical picture that requires a specially-trained and experienced concussion clinician to solve. As the largest global provider of concussion treatment and rehabilitation, Complete Concussions certified clinicians are ready to help find the root-cause of lingering symptoms.
StatPearls
A few common symptoms seen in patients with postconcussive syndrome include headache, fatigue, vision changes, disturbances in balance, confusion, dizziness, insomnia, and difficulty concentrating. Approximately 90 percent of concussion symptoms are transient, and symptoms typically resolve within 10 to 14 days. However, symptoms may linger for weeks. Persistent postconcussive syndrome occurs when symptoms persist beyond 3 months.
