    Notes: Summary In familial amyotrophic lateral sclerosis associated with dementia there was symmetrical involvement of the amygdala, insula, and fronto-temporal cortex. The cortical lesions were most severe in the superior frontal gyri and the infero-lateral temporal lobes, while the adjacent cingulate gyri and hippocampi were spared. One patient with dementia and another with slight mental abnormality had cerebral lesions which varied in extent, but were of the same type and pattern. Although the clinical and histological findings are variable, the disease seems to be a distinct entity, closely allied to amyotrophic lateral sclerosis, but also having features in common with Guamanian amyotrophic lateral sclerosis, and amyotrophic lateral sclerosis-dementia complex of sporadic occurrence.

    Notes: Summary Nerve Growth Factor (NGF) antiserum causes neuronal loss in the sympathetic ganglia of newborn rats. Pre and post ganglionic sympathetic fibers from eleven such animals and eight controls were studied by phase contrast and electron microscopy. Quantitative techniques were applied to the study of different parameters of the axons and Schwann cells. Treated animals showed only 24% of the axonal population of controls and 34% of Schwann cells. This fiber loss was non-selective, affecting all fiber sizes. Schwann cells from treated animals enclosed fewer axons than normal and some contained none. Contrary to what is seen following transection of an unmyelinated nerve, regenerative axonal sprouting was not observed during the 6 week period studied. Schwann cell processes were elongated and unfolded, frequently engulfing bundles of collagen. NGF antiserum experiments provide a tool for the study of axonal and Schwann cell behaviour after neuronal loss avoiding the disadvantages of the traumatic disruption of neural architecture that results from experimental surgical lesions.
