Abstract
In this work, we designed, synthesised and biologically investigated a novel series of 14 N- and O-phosphorylated tacrine derivatives as potential anti-Alzheimer’s disease agents. In the reaction of 9-chlorotacrine and corresponding diamines/aminoalkylalcohol we obtained diamino and aminoalkylhydroxy tacrine derivatives. Next, the compounds were acid to give final products 6–13 and 16–21 that were characterised by 1H, 13 C, 31 P NMR and MS. The results of the docking studies revealed that the designed phosphorus hybrids, in theory can bind to AChE and BChE. All compounds exhibited significantly lower AutoDock Vina scores compared to tacrine. The inhibitory potency evaluation was performed using the Ellman’s method. The most inhibitory activity against AChE exhibited compound 8 with an IC50 value of 6.11 nM and against BChE 13 with an IC50 value of 1.97 nM and they were 6- and 12-fold potent than tacrine. Compound 19 showed the lack of hepatocytotoxicity in MTT assay.

Abstract
OBJECTIVE Anticholinergic and sedative medications are associated with acute cognitive impairment, but the long-term impact on change in cognition is unclear. This study investigated the effect of anticholinergic and sedative medications, quantified using the Drug Burden Index (DBI), on change in cognition over time in community-dwelling older men. METHODS This was a prospective cohort study of men aged ≥70 years in Sydney, Australia. DBI was assessed at baseline, 2, and 5 years. Cognitive performance was assessed using the Mini-Mental State Exam (MMSE) at each wave. Logistic quantile mixed-effects modelling was used to assess the adjusted effect of DBI on the median MMSE-time profile. Analyses were restricted to men with English-speaking backgrounds (n = 1059, 862, and 611 at baseline, 2, and 5 years). RESULTS Overall, 292 (27.7%), 258 (29.9%), and 189 (31.3%) men used anticholinergic or sedative medications at baseline, 2, and 5 years. There was a concave relationship between MMSE and time, where higher DBI corresponded to lower MMSE scores (coefficient: -0.161; 95% CI: -0.250 to -0.071) but not acceleration of declining MMSE over time. CONCLUSIONS Exposure to anticholinergic and sedative medications is associated with a small impairment in cognitive performance but not decline in cognition over time. KEY MESSAGES Exposure to anticholinergic and sedative medications, quantified using the Drug Burden Index, is associated with small cross-sectional impairments in cognitive performance. There was no evidence that exposure to anticholinergic and sedative medications is associated with accelerating decline in cognitive performance over a 5-year follow-up. Older people taking anticholinergic and sedative medications may derive immediate but small benefits in cognitive performance from clinical medication reviews to minimize or cease prescribing of these medications.

Abstract
Behavioral and psychological symptoms of dementia (known also as neuropsychiatric symptoms) are essential features of Alzheimer's disease and related dementias. The near universal presence of neuropsychiatric symptoms in dementia (up to 90% of cases) has brought significant attention of clinicians and experts to the field. Non-pharmacological and pharmacological interventions are recommended for various types of neuropsychiatric symptoms. However, most pharmacological interventions for the treatment of behavioral and psychological symptoms of dementia are used off-label in many countries. Cognitive decline and neuropsychiatric symptoms can be linked to alterations in multiple neurotransmitter systems, so modification of abnormalities in specific systems may improve clinical status of patients with neuropsychiatric symptoms. Use of serotonergic compounds (novel particles acting on specific receptors and widely acting drugs) in the treatment of neuropsychiatric symptoms is reviewed.

Abstract
OBJECTIVES Psychotic symptoms associated with Alzheimer Disease (AD) contribute to excess functional dependence. Longitudinal studies have generally examined the association between rates of functional decline and the occurrence of psychotic symptoms from either a single evaluation or from multiple evaluations rather than through changes in frequency and severity of symptoms. Although the presence or absence of psychotic symptoms at initial or follow-up examinations may be associated with changes in functional status, the nature of the relationship between changes in these domains cannot be inferred. We examine the association between changes in the frequency of psychotic symptoms and changes in dependence in activities of daily living (ADL) over a period ranging from 1 to 74 months (median = 17.7). METHOD Data from a cohort of 234 individuals referred to a memory clinic were analyzed using multilevel linear regression. Information on ADL, behavioral and psychological symptoms, depression, and cognition was collected. RESULTS An increase in the frequency of psychotic symptoms had a unique influence on the deterioration of basic ADL, after controlling for demographic variables, changes in cognition, depression, and other behavioral and psychological symptoms (B = -.017, p = .003). However, changes in psychotic symptoms did not significantly contribute to declines in the ability to perform instrumental ADL (B = -.008, p = .439). CONCLUSION Changes in psychotic symptoms may influence basic but not instrumental ADL over time. These findings may have ramifications for studies and treatment plans for individuals with AD who demonstrate psychotic symptoms.
