Definition: Arises as a delayed or protracted response to a stressful event or situation (of either brief or long duration) of an exceptionally threatening or catastrophic nature, which is likely to cause pervasive distress in almost anyone. Predisposing factors, such as personality traits (e.g. compulsive, asthenic) or previous history of neurotic illness, may lower the threshold for the development of the syndrome or aggravate its course, but they are neither necessary nor sufficient to explain its occurrence. Typical features include episodes of repeated reliving of the trauma in intrusive memories ( flashbacks ), dreams or nightmares, occurring against the persisting background of a sense of numbness and emotional blunting, detachment f ...[+++]rom other people, unresponsiveness to surroundings, anhedonia, and avoidance of activities and situations reminiscent of the trauma. There is usually a state of autonomic hyperarousal with hypervigilance, an enhanced startle reaction, and insomnia. Anxiety and depression are commonly associated with the above symptoms and signs, and suicidal ideation is not infrequent. The onset follows the trauma with a latency period that may range from a few weeks to months. The course is fluctuating but recovery can be expected in the majority of cases. In a small proportion of cases the condition may follow a chronic course over many years, with eventual transition to an enduring personality change (F62.0). | Traumatic neurosis

Definition: Alzheimer's disease is a primary degenerative cerebral disease of unknown etiology with characteristic neuropathological and neurochemical features. The disorder is usually insidious in onset and develops slowly but steadily over a period of several years.

In view of the latency periods of some quarantine pests, and the time required for the detection of the source of infestation, records should be kept for at least three years.

What we know is that poor conditions of the past and the fact that there's a long latency period from exposure to high levels of chrysotile or any kind of asbestos for a long period of time create industrial diseases.

44. Recognises that, due to very long latency periods, asbestos victims are often unable to substantiate the causality of their occupational asbestos exposures;

AE. whereas due to the very long latency period and due to the lack of knowledge among medical staff, victims often do not receive timely and proper support from healthcare providers;
