Cognitive test performance and presence of subclinical cardiovascular disease in the cardiovascular health study.
The purpose of the present study was to investigate the relationship between performance on a comprehensive battery of neuropsychological tests and the presence of clinical, subclinical or no cardiovascular disease in an elderly community-dwelling population. The results confirm previous reports of significant associations of age, education and gender with test performance. When performance was examined controlling for these variables, significant associations of disease group were seen with five measures emphasizing speed of performance; Parts A and B of the Trail Making Test, the WAIS-R Digit Symbol and Block Design subtests and category verbal fluency. These results add to the evidence that, in addition to other health implications, cardiovascular disease is related to cognitive functioning in the elderly even at subclinical levels.
Effect of microaerosol inhalation on the pattern of breathing.
Microaerosol stimulation of the trachea and bronchi appears to have no effect on the pattern of breathing. However, laryngeal stimulation with microaerosol produces consistent changes characterized by slowing of the inspiratory effort. The reflex response can be abolished by either bilateral superior laryngeal nerve section or topical anesthesia of the laryngeal mucous membranes. Nasal stiumulation with saline microaerosol results in marked slowing of inspiration. This response can also be blocked by topical anesthesia of the nasal mucosa. The decreased breathing rate results from both increased t insp. and t exp. During inspiration the build-up phrenic discharge activity, the phrenic slope, decreases. The phrenic peak, however, remains unchanged. The nose and larynx, therefore, appear to play significant roles in the modification of the breathing pattern in response to a nonirritating solution delivered as a microaersol. Slower breathing, relexly produced in the human being by such a method, might benefit partial airway obstruction by reducing turbulence and therefore the work of breathing. It is speculated that in a marginally competent upper airway, this benefit might be a critical factor in survival.
