By 1934 the current concept of PCS had replaced ideas of hysteria as the cause of post-concussion symptoms. [18] British authorities banned the term shell shock during World War II to avoid an epidemic of cases, and the term posttrauma concussion state was coined in 1939 to describe "disturbance of consciousness with no immediate or obvious ...
Determining the ideal time for a person to return to work will depend on personal factors and job-related factors including the intensity of the job and the risk of falling or hitting one's head at work during recovery. [14] After the required initial recovery period of complete rest (24–48 hours after the concussion began), gradually and ...
Second-impact syndrome (SIS) occurs when the brain swells rapidly, and catastrophically, after a person has a second concussion before symptoms from an earlier one have subsided. This second blow may occur minutes, days, or weeks after an initial concussion, [1] and even the mildest grade of concussion can lead to second impact syndrome. [2]
Among the elderly, falls lead to hundreds of thousands of hip fractures every year and are the most common cause of traumatic brain injury. Most striking is that falls are the number one cause of ...
Visual impairments, glaucoma, macular degeneration and retinopathy increase the risk of falling and of hip fractures. [ 14 ] Bifocals and trifocals can increase the risk of falling as the lower portion of corrective lenses are optimized for distances approximately 18 in (46 cm), thus precluding clear vision of one's feet/floor, approximately 4. ...
A hip fracture is a break that occurs in the upper part of the femur (thigh bone), at the femoral neck or (rarely) the femoral head. [2] Symptoms may include pain around the hip, particularly with movement, and shortening of the leg. [2] Usually the person cannot walk. [3] A hip fracture is usually a femoral neck fracture.
But the recovery time can vary. Up to about 1/3 of people experience persisting symptoms after concussion (PHAC) or persistent post concussion symptoms (PPAC), defined as symptoms that last more than 4 weeks. [5] [6] [7] After an injury, concussion symptoms can begin immediately or be and delayed by 1-2 days at most. [8]
