SENESCENCE AND DEMENTIA “An old man is twice a child” Shakespeare (Hamlet) SENESCENCE/AGING Senescence (Latin, senex: “old man” or “old age”) is the combination of processes which follow the period of development of an organism. Aging is generally characterized by declining ability to respond to stress and increased risk of disease. Accordingly, death may be seen as the inevitable consequence of aging. A controversial view is that aging is itself a “disease” which may be curable. A related and interesting definition: Aging represents a state of complex multifactorial pathways that involve and ongoing molecular, cellular, and organ damage causing functional loss, disease vulnerability and eventual death (Fontana et al, 2010). Memory loss is a less prominent feature of normal ageing than has sometimes been supposed. Healthy older people do not perform quite as well on objective memory tests as healthy younger people. However, normal aging does not cause functional decline, and ability to perform the normal activities of daily living is maintained. As we get older we slow down both physically and mentally. It takes longer to do normal tasks, including mental tasks like calculations and solving puzzles. It also takes longer to interpret new information, particularly visual-spatial information – which explains why older drivers have more accidents at intersections than on the open road. Executive function and the ability to put together the “big picture” also declines with age. This may explain why some people who have functioned in highly demanding roles are “perfectly happy”, in retirement, to occupy themselves with “odd-jobs about the house”. While these people may have filled their lives with many new activities, slowing down of mental functions and greater focus on details may also partly underpin this happy state of affairs. When people with mild cognitive problems are followed up for 5 years, 80% have developed dementia (Godinho et al, 2011). A recent study of people over 65 years found – cognitive impairment but no dementia, 14. The clustering of white matter lesions (WML) in the temporal region identifies individuals at increased risk of both mild-NCD or dementia (Mortamais et al, 2013). Apathy in mild-NCD and dementia is associated with abnormalities in the frontal regions and anterior cingulate (Stella et al, 2013).

Thus, acute exposure to these compounds is con- genic 5-HT2A agonists such as LSD and mescaline produce sidered a useful pharmacologic tool for producing some as- similar deficits in startle habituation in rats (59,74). Con- pects of schizophrenic symptomatology in the laboratory versely, opposite behavioral effects are produced by 5-HT2A animal. Simi- Several interesting aspects of this model distinguish it larly, the PPI-disruptive effects of hallucinogenic 5-HT2- from monoamine-based models. For example, the behav- receptor agonists are blocked by the selective 5-HT2A antag- ioral effects of PCP and related compounds are not, for the onist M100907, but not by the dopamine blocker haloperi- most part, mediated by increased dopamine transmission dol (74). Furthermore, in keeping with the similarities be- and therefore are not blocked by typical antipsychotics (see tween acute psychotic states and the syndrome induced by below). Similarly, in normal human volunteers, the psy- hallucinogens, latent inhibition is also disrupted by LSD chotomimetic effects of ketamine are not blocked by typical and other serotoninergic hallucinogens (75), as it is in antipsychotics, but they are reduced significantly by the pro- acutely ill schizophrenic patients. These effects can be totypal atypical antipsychotic clozapine (79). Therefore, this blocked by the putative antipsychotic M100907 (75). Thus, model may be especially useful for testing the effectiveness the effects of hallucinogens on habituation, PPI, and latent of atypical and perhaps even novel antischizophrenia drugs. The construct validity of this model is based been based on preclinical PCP models (41,80). Another on compelling evidence that both the symptoms of schizo- attractive aspect of the NMDA antagonist model is that, phrenia and the effects of hallucinogens reflect exaggerated unlike the dopamine-based models, it has strong construct responses to sensory and cognitive stimuli, theoretically re- validity for studying the cognitive and attentional deficits sulting from failures in normal filtering or gating processes in schizophrenia.

This finding suggests the possibility of groups (81). These drugs produce both locomotor hyperactivity and stereotyped behaviors. Al- Glutamatergic Models though they also increase dopamine neurotransmission in Dysfunctional glutamate neurotransmission has been impli- limbic regions (82), their motor-activating effects appear to cated in schizophrenia, primarily because noncompetitive be dopamine-independent (83). At rather low doses, PCP antagonists of the NMDA subtype of glutamate receptors, retards habituation of the startle response without affecting including PCP and ketamine, produce a behavioral syn- startle reactivity (84), a pattern similar to that seen in paral- drome in healthy humans that closely resembles symptoms lel studies in schizophrenic patients (9). Also as in schizo- of schizophrenia and is frequently misdiagnosed as acute phrenia, PCP-treated rats exhibit marked deficits in social schizophrenia (77,78). Although typical antipsychotics have no reliable symptoms, such as paranoia, agitation, and auditory halluci- effect on the PCP-induced disturbance in social behavior nations; negative symptoms, such as apathy, poverty of in rats, the atypical antipsychotics clozapine, sertindole, and thought, and social withdrawal; and cognitive deficits, such olanzapine appear to reverse the effects partially (22).

As with apomorphine and as in schiz- pharmacologic models of schizophrenia in both basic and ophrenia, both intramodal and cross-modal PPI is sensitive clinical studies. Notably, whereas psychotic episodes are to noncompetitive NMDA antagonists (59).
