Susan Anderson (psychotherapist)
While Kübler-Ross, Anderson, and others have attempted to define discrete stages of grief, such as an initial period of numbness leading to depression and finally to reorganization and recovery, most modern grief specialists recognize the variations and fluidity of grief experiences, that differ considerably in intensity and length among cultural groups and from person to person. No grief stage theory has been able to account for how people cope with loss, why they experience varying degrees and types of distress at different times, and how or when they adjust to a life without their loved one over time.
Rabies in animals
Three stages of rabies are recognized in dogs. The first stage is a one- to three-day period characterized by behavioral changes and is known as the prodromal stage. The second stage is the excitative stage, which lasts three to four days. It is this stage that is often known as "furious rabies" due to the tendency of the affected dog to be hyperreactive to external stimuli and bite at anything near. The third stage is the paralytic stage and is caused by damage to motor neurons. Incoordination is seen due to rear limb paralysis and drooling and difficulty swallowing is caused by paralysis of facial and throat muscles. Death is usually caused by respiratory arrest.
