Photophobia is considered the second most common symptom of both concussion and post-concussion syndrome. Soldiers on duty experience photophobia after blast-related concussions or mild traumatic brain injury in 60-75% of instances. In addition, soldiers report other symptoms, such as asthenopia, squinting, dry eyes and headaches, for which they are considered to be at high risk. According to the International Brain Injury Association, some concussed patients report indirect symptoms such as multi-tasking difficulties, dizziness, vertigo, and fatigue. Moreover, some concussed individuals experience photophobia for approximately 6 months or indefinitely. We present the case of a 23-year-old soldier who presented with severe photophobia after a mild traumatic head injury. His photophobia was alleviated after the administration of topical anaesthetic drops in the eyes in the absence of any ocular surface pathology. He was diagnosed with post-concussion syndrome light sensitivity and was managed successfully with rose-coloured special photophobia glasses tinted with FL-41. Photophobia is a common neurological symptom in military personnel that needs more attention as it affects body and mind. We have reported an uncommon pathway of photophobia, which may unveil an unrecognised mechanism that may play a role in post-concussion photophobia.

Background/objectives: The auditory middle-latency responses (AMLRs) assess central sensory processing beyond the brainstem and serve as a measure of sensory gating. They have clinical relevance in the diagnosis of neurological conditions. In this study, magnitude and habituation of the AMLRs were tested for sensitivity and specificity in classifying dizzy patients with vestibular migraine (VM) and post-concussive syndrome.

Importance: There has been a great deal of interest in mild traumatic brain injury (mTBI) and posttraumatic stress disorder (PTSD) and their association with one another, yet their interaction and subsequent associations with long-term outcomes remain poorly understood.
Objective: To compare the long-term outcomes of mTBI that occurred in the context of psychological trauma (peritraumatic context) with mTBI that did not (nonperitraumatic context).
Design, Setting, And Participants: This cohort study of post-9/11 US veterans used data from the Translational Research Center for Traumatic Brain Injury and Stress Disorders (TRACTS) study at the Veterans Affairs Boston Healthcare System, which began in 2009; the current study utilized data from baseline TRACTS visits conducted between 2009 and 2024.

Individuals with mild traumatic brain injury (mTBI) exhibit significant accommodative abnormalities. Accommodation microfluctuation (MFs) plays an important role in the accommodation steady-state control. This study was set to investigate the characteristics of the MFs in mTBI subjects and whether chromatic filter (CF) or neutral density filter (ND) would impact these parameters.

Persisting symptoms after concussion (PSaC) affect up to 30% of children, adolescents, and young adults beyond 1 month post-injury, posing challenges in clinical care. This retrospective study examined 54 patients referred for neuropsychological evaluation due to PSaC, exploring factors contributing to symptom persistence. Results showed that 75.

Post-Concussion Syndrome (PCS) represents a complex constellation of symptoms that persist following a concussion or mild traumatic brain injury (mTBI), with significant implications for patient care and outcomes. Despite its prevalence, diagnosing PCS presents considerable challenges due to the subjective nature of symptoms, the absence of specific diagnostic tests, and the overlap with other neurological and psychiatric conditions. This review explores the multifaceted diagnostic challenges associated with PCS, including the heterogeneity of symptom presentation, the limitations of current neuroimaging techniques, and the overlap of PCS symptoms with other disorders.
