The deficiency model: an exploration of current approaches to late-life disorders.

Many of the terms used to describe conditions in elderly individuals, whether medical (deterioration, involution, degeneration) or neurobehavioral (impairment, dysfunction), imply deficiency. The complex of distorted views of real impairment, illness, or disability may be described as the deficiency model. Although developmental theory has expanded explosively and could offer an alternative frame of reference to dispel denigration of the elderly condition, late life continues to be viewed as lacking all redeeming aspects, while mortality is considered an obstacle to prolonging life rather than one of its determinants. Deficiency-model thinking has influenced the conduct of epidemiologic, neurobiologic and clinical research, whose results in turn have often been interpreted to reinforce such thinking. It can also distort clinical approaches to diagnosis and treatment of late-life disorders. This paper offers instead an alternative approach that focuses on late life as a developmental task.

Stereology, a complement to experimental neuropathology. I. Introduction into stereology. II. Ultrastructural-morphometric investigations (baseline data, axotomy) on the superior cervical ganglion of the rat.

This paper first gives a short introduction into the principles of stereology. It shows then its actual application to the assessment of ultrastructural-morphometric data of the normal superior cervical ganglion of the rat (base-line data) and after axotomy. In the early phase after axon transsection the volumetric composition of the superior cervical ganglionic neuron remains constant. Only the volume density of the lysosomal forms is significantly increased from 0.9--3.2%. Ultrastructural morphometric analysis of the rough endoplasmic reticulum does not provide any information on quantitative changes underlying the phenomenon of central chromatolysis.
