Summary
This study found no significant cognitive decline in lacrosse players after multiple head impacts. However, subtle cognitive changes may not be detected by current testing methods.
Area of Science:
- Sports Medicine
- Neuroscience
- Biomechanics
Background:
- Understanding head impacts is crucial for assessing effects beyond clinical concussion.
- Repeated sub-concussive impacts may have cumulative effects on cognitive function.
- Investigating cognitive changes in athletes is vital for player safety and long-term health.
Purpose of the Study:
- To determine the correlation between head impacts and cognitive test performance in collegiate lacrosse players.
- To assess changes in neurocognitive function from pre-season to post-season.
- To evaluate the relationship between the number of head impacts and cognitive outcomes.
Main Methods:
- A case-control study involving 34 NCAA Division I men's lacrosse players.
- Head impacts were measured using instrumented helmets with accelerometers during the 2014 season.
- Cognitive function was assessed using the Sport Concussion Assessment Tool (SCAT 3) and Concussion Vital Signs (CVS) tests pre- and postseason.
Main Results:
- No significant difference was found in SCAT 3 scores between pre- and postseason.
- A significant negative correlation (r = -0.362, P = .035) was observed between SCAT 3 scores and the total number of head impacts.
- Improvements were noted in some CVS components (visual reaction time, reaction time, simple reaction time), but no correlation with head impacts was found.
Conclusions:
- The study did not detect cognitive declines in athletes experiencing multiple head impacts without clinical concussion.
- It remains undetermined if subtle cognitive declines occurred that were below the detection threshold of SCAT 3 and CVS.
- Further research is needed to explore sensitive methods for detecting sub-clinical cognitive changes from head impacts.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Social psychologists analyze how groups influence one another, shaping social structures and interactions through both cooperation and competition. These dynamics manifest in various ways, ranging from economic partnerships to intergroup conflicts that shape societal structures and perceptions.Cooperation and Competition in Intergroup RelationsIntergroup relationships vary across contexts, sometimes fostering cooperation and mutual benefit while at other times leading to conflict and...

01:19Muscles that Move the Head
6.0K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Impact occurs when two bodies collide, leading to the application of impulsive forces between them. Analyzing impact mechanics involves considering two colliding particles moving along a line known as the line of impact, which passes through their centers and is perpendicular to the contact plane.
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

1.3K
Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...
