AbstractGait disorders are common in the elderly as there are various causes of neurological and non-neurological conditions. On the other hand, most of the gait parameters do change with advancing age which is identified as age-related physiological changes in gait. At this point, the discrimination between age-related physiological changes and gait disorders may be strictly challenging. After identifying gait as an abnormal pattern, classification of it and making the responsible pathophysiology also require high-level expertise in this regard. Herein, we present a rare patient with corticobasal degeneration (CBD) who had admitted initially due to complaints of gait problems. Over a long time, the patient had received the misdiagnosis of gait abnormality due to musculoskeletal problems by multiple physicians. However, the detailed neurological exam showed a higher level gait disorder (HLGD). Further investigations at this point yielded the diagnosis of CBD.

Cough is one of the most common causes of seeking the primary medical care, especially during the autumn and the spring. This article is a review of literature  aimed at differential diagnosis of possible causes of acute cough in children and  adults. Given a vast majority of diseases associated with cough, differential diagnosis  have to consider several issues. The key issue is cough duration and possible  anatomical location of the pathological changes. An algorithm of differential diagnosis  of acute cough in children and adults and description of most common diseases  associated with acute cough are given in the review. Further diagnostic work-up  should be driven by the duration of cough as soon as the acute cough could be first  manifestation of a chronic disease.

The prevalence of syncope rises with age and is challenging because of atypical presentation, overlap with falls, and poor recall of events. Cardiac causes and multiple comorbidities are more common, and related morbidity and mortality are higher than in younger patients. Hence, a high index of suspicion for cardiovascular causes of falls and dual pathology will increase successful diagnosis and intervention. Age-related neurohumoral and physiological changes plus chronic diseases and medications often contribute to syncope. Orthostatic hypotension, carotid sinus syndrome, vasovagal syncope, postprandial syncope, sinus node disease, atrioventricular block, and ventricular tachycardia are other common causes. Management is often based on removing or reducing the predisposing or precipitating factors through medication adjustments, behavioural strategies, and more invasive cardiac interventions if indicated. It is often not possible to identify a single cause of syncope in older persons, hence apragmatic management of each diagnosis is recommended.

SUMMARY:The morphological, chemical, and physiological changes in the brain accompanying old age are reviewed. The deterioration of the striatal and hypothalamic dopaminergic systems were implicated in the onset of age related Parkinsonian-like slowing of performance and altered affect. Cholinergic hippocampal and neocortical systems were chemically and physiologically abnormal in the aged. The implications for slowed cognitive processing and persistance of the memory trace are presented.

In domestic animals in postnatal ontogenesis, statistically significant changes in the number of α-endocrinocytes and the values of their nuclear-cytoplasmic ratio in the endocrine islets of pancreas have been revealed, which reflects the species and age-related dynamic processes of its morphofunctional development in animals. In cattle and small cattle (sheep), pigs, dogs and cats, two critical periods of postnatal development of the pancreas have been identified. The first critical period is observed from the birth to the age of three months. It is associated with an alimentary factor: the transition from a dairy diet to roughage, which leads to a decrease in the values of morphometric indicators of the pancreas and the restructuring of the functional work of the organ as a whole. The second critical period is registered in animals during puberty, that is, at 6 months of age, which is associated with the release of hormonal inducers aimed primarily at the implementation of physiological changes in the body.

Abstract Cholinesterase activity in human erythrocytes was determined in 1903 blood samples by the "pH-stat" method. Differences in activity were examined as a function of sex, age, and pregnancy. Reliability intervals for the population average and approval or normality intervals for individual values were established. Sex- and age-related differences were very significant.

Disequilibrium is one of the most common complaints that older adults bring to their physician and falling is a frequent complication; because of the increasing number of elderly patients in western society the problem grows. The increasing susceptibility to falling can be consequence of age-related physiological changes and of a higher prevalence of comorbidities causing dizziness, vertigo and imbalance; these symptoms can worse the already poor balance of old adults increasing the risk of falling. Among the major reasons of vertigo and dizziness, central vertigo and orthostatic vertigo are very common; also vestibular disorders have a great role and are currently thought to account for 48% of dizziness reported by older adults. An early identification of the treatable condition underlying dizziness in elderly would surely ameliorate the outcome of these patients.
