Diffuse Axonal Injury

Diffuse axonal injury (DAI) is one of the most common and devastating types of traumatic brain injury, meaning that damage occurs over a more widespread area than in focal brain injury. DAI, which refers to extensive lesions in white matter tracts, is one of the major causes of unconsciousness and persistent vegetative state after head trauma. It occurs in about half of all cases of severe head trauma and also occurs in moderate and mild brain injury.

The outcome is frequently coma, with over 90% of patients with severe DAI never regaining consciousness. Those who do wake up often remain significantly impaired.

Nowadays, other authors state that DAI can occur in every degree of severity from (very) mild or moderate to (very) severe. Concussion may be a milder type of diffuse axonal injury.

Famous quotes containing the words injury and/or diffuse:

    A great proportion of architectural ornaments are literally hollow, and a September gale would strip them off, like borrowed plumes, without injury to the substantials.... What if an equal ado were made about the ornaments of style in literature, and the architects of our bibles spent as much time about their cornices as the architects of our churches do? So are made the belles-lettres and the beaux-arts and their professors.
    Henry David Thoreau (1817–1862)

    [T]he syndrome known as life is too diffuse to admit of palliation. For every symptom that is eased, another is made worse. The horse leech’s daughter is a closed system. Her quantum of wantum cannot vary.
    Samuel Beckett (1906–1989)
