Alzheimer's disease (AD) and frontotemporal dementia (FTD) are the most common types of progressive neurodegenerative disorder in our catchment area. The distribution of cortical degeneration in FTD is mainly the reverse of that in AD, while there are both differences and similarities in the clinical characteristics. Somatostatin and neuropeptide Y (NPY) are neuropeptides with a widespread distribution in the human cerebral cortex. Somatostatin is involved in the regulation of hormone release from the anterior pituitary and may act as a neurotransmitter-modulator. NPY is a potent anxiolytic neuropeptide. Somatostatin and NPY coexist in the cerebral cortex, basal ganglia and in amygdaloid complexes. The present study of AD (n = 34) and FTD (n = 22) analyses the cerebrospinal-fluid (CSF) levels of somatostatin-like immunoreactivity and NPY-like immunoreactivity and correlates their levels to 54 different clinical items, such as restlessness, anxiety, irritability and depression. The CSF levels of the two neuropeptides somatostatin and NPY were significantly correlated in FTD (p < 0.02), but not in AD. Several significant correlations to the clinical signs were found: in AD disorientation and dyspraxia, and in FTD agitation, irritability and restlessness. Somatostatin showed a significant negative correlation with severity of dementia in AD (p < 0.013).

Disorientation, muscle fasciculations and weakness seen in a 12-year-old neutered female domestic shorthaired cat were attributed to hypoglycaemia associated with a large hepatoma. Glucagon tolerance tests on this cat and a healthy cat showed that their plasma glucose concentrations increased and decreased at about the same rate. Plasma insulin concentrations in the healthy cat increased and decreased in parallel with the plasma glucose concentration. In the affected cat, plasma insulin concentrations increased initially but decreased more rapidly. Reflecting these observations, the amended insulin to glucose ratios in the affected cat were much lower than those of the healthy cat, until the 4-hour sample. Serum somatostatin, somatomedin and gastrin concentrations were measured but no conclusions as to pathogenesis of the hypoglycaemia could be made. The alterations in insulin secretion in the affected cat suggested that altered hormonal control of glucose homeostasis may have occurred with this tumour.
