Counseling, supported employment and community support services may also be useful. TBI is a major cause of death and disability worldwide, especially in children and young adults. Males sustain traumatic brain injuries around twice as often as females. The 20th century saw developments in diagnosis and treatment that decreased death rates and improved outcomes. Classification
Traumatic brain injury is defined as damage to the brain resulting from external mechanical force, such as rapid acceleration or deceleration, impact, blast waves, or penetration by a projectile. Brain function is temporarily or permanently impaired and structural damage may or may not be detectable with current technology.TBI is one of two subsets of acquired brain injury (brain damage that occur after birth); the other subset is non-traumatic brain injury, which does not involve external mechanical force (examples include stroke and infection). All traumatic brain injuries are head injuries, but the latter term may also refer to injury to other parts of the head. However, the terms head injury and brain injury are often used interchangeably. Similarly, brain injuries fall under the classification of central nervous system injuries and neurotrauma. In neuropsychology research literature, in general the term "traumatic brain injury" is used to refer to non-penetrating traumatic brain injuries. TBI is usually classified based on severity, anatomical features of the injury, and the mechanism (the causative forces). Mechanism-related classification divides TBI into closed and penetrating head injury. A closed (also called nonpenetrating, or blunt) injury occurs when the brain is not exposed.
Postpartum blues, also known as baby blues and maternity blues, is a very common but self-limited condition that begins shortly after childbirth and can present with a variety of symptoms such as mood swings, irritability, and tearfulness. Mothers may experience negative mood symptoms mixed with intense periods of joy. Up to 85% of new mothers are affected by postpartum blues, with symptoms starting within a few days after childbirth and lasting up to two weeks in duration. Treatment is supportive, including ensuring adequate sleep and emotional support. If symptoms are severe enough to affect daily functioning or last longer than two weeks, the individual should be evaluated for related postpartum psychiatric conditions, such as postpartum depression and postpartum anxiety. It is unclear whether the condition can be prevented, however education and reassurance are important to help alleviate patient distress. Signs and symptoms
Symptoms of postpartum blues can vary significantly from one individual to another, and from one pregnancy to the next. Many symptoms of postpartum blues overlap both with normal symptoms experienced by new parents and with postpartum depression. Individuals with postpartum blues have symptoms that are milder and less disruptive to their daily functioning compared to those with postpartum depression. Symptoms of postpartum blues include, but are not limited to:
Tearfulness or crying "for no reason"
Mood swings
Irritability
Anxiety
Questioning ones ability to care for the baby
Difficulty making choices
Loss of appetite
Fatigue
Difficulty sleeping
Difficulty concentrating
Negative mood symptoms interspersed with positive symptoms

Onset
Symptoms of postpartum blues generally begin within a few days of childbirth and often peak by day four or five.
