Suicide is a global phenomenon in all regions of the world affecting people of all age groups. It has detrimental consequences on patients, their families, and the community as a whole. There have been numerous risk factors described for suicide including mental illness, stressful life situations, loss of social support, and general despair. The association of suicide with Islam has not been extensively studied. The common impression from clinical practice is that being a practicing Muslim reduces the risk of suicide. Another factor associated with suicide is starting a patient on antidepressants. However, this has been questioned recently. This report describes a middle-aged man with depression and multiple social stressors who survived a serious suicide attempt. The discussion will focus on the factors that lead him to want to end his life and the impact of the assumed protective factors such as religious belief and family support on this act of self-harm. Such patients can be on the edge when there is an imbalance between risk factors (such as depression, insomnia, and psychosocial stressors) and protective factors (like religious affiliation and family support). All physicians are advised to assess the suicide risk thoroughly in patients with depression regardless of any presumed protective factor.

Introduction We investigated the frequency, neuropathology, and phenotypic characteristics of spastic paraplegia (SP) that precedes dementia in presenilin 1 (PSEN1) related familial Alzheimer's disease (AD). Methods We performed whole exome sequencing (WES) in 60 probands with hereditary spastic paraplegia (HSP) phenotype that was negative for variants in known HSP‐related genes. Where PSEN1 mutation was identified, brain biopsy was performed. We investigated the link between HSP and AD with PSEN1 in silico pathway analysis and measured in vivo the stability of PSEN1 mutant γ‐secretase. Results We identified a PSEN1 variant (p.Thr291Pro) in an individual presenting with pure SP at 30 years of age. Three years later, SP was associated with severe, fast cognitive decline and amyloid deposition with diffuse cortical plaques on brain biopsy. Biochemical analysis of p.Thr291Pro PSEN1 revealed that although the mutation does not alter active γ‐secretase reconstitution, it destabilizes γ‐secretase‐amyloid precursor protein (APP)/amyloid beta (Aβn) interactions during proteolysis, enhancing the production of longer Aβ peptides. We then extended our analysis to all 226 PSEN1 pathogenic variants reported and show that 7.5% were associated with pure SP onset followed by cognitive decline later in the disease. We found that PSEN1 cases manifesting initially as SP have a later age of onset, are associated with mutations located beyond codon 200, and showed larger diffuse, cored plaques, amyloid‐ring arteries, and severe CAA. Discussion We show that pure SP can precede dementia onset in PSEN1‐related familial AD. We recommend PSEN1 genetic testing in patients presenting with SP with no variants in known HSP‐related genes, particularly when associated with a family history of cognitive decline.

Aims and methodThis study used data collected to describe the activity, case-load characteristics and outcome measures for all patients seen during a 6-year period.ResultsThe service reviewed 2153 patients over 6 years with referral rates and case-load characteristics comparable to those described in a previous study period. The team saw 82% of patients on the day they were referred. Data and outcome measures collected showed significant complexity in the cases seen and statistically significant improvement in Health of the Nation Outcome Scales (HoNOS) scores following service input.Clinical implicationsThe outcome measures used were limited, but the study supports the need for specialist liaison psychiatry for older adults (LPOA) services in the general hospital. The Framework of Outcome Measures – Liaison Psychiatry has now been introduced, but it remains unclear how valid this is in LPOA. It is of note that cost-effectiveness secondary to service input and training activities are not adequately monitored.Declaration of interestNone.
