Background: Posttraumatic stress disorder (PTSD) is considered an independent risk factor for dementia. Despite the (clinical) evidence that PTSD is associated with neuropsychiatric symptoms in people with dementia, studies on its prevalence and clinical manifestation are limited, and their quality is affected by the lack of a structured method to...

Objectives:Approximately one third of older adults (≥ 60 years) with a posttraumatic stress disorder (PTSD) also suffer from a comorbid personality disorder. Emerging evidence shows that in Eye Movement Desensitization and Reprocessing (EMDR) therapy can be beneficial for personality disorders. Since personality disorders are associated with severa...

Background: Assessment of Posttraumatic Stress Disorder (PTSD) symptoms in individuals with dementia is difficult due to diagnostic challenges like an incomplete self-report, interference of neuropsychiatric symptoms and overlapping comorbid psychiatric symptoms. Objective: These diagnostic challenges are articulated here and an in-depth evaluation...

Introduction: Pharmacotherapy in older adults with personality disorders (PDs) can be even more complicated compared to younger adults, because older adults stand at risk for polypharmacy and its negative consequences due to somatic comorbidities and biological age-related changes. Aims: This study’s primary objective serves to describe the point p...

Objectives In older adults, PTSD is associated with decreased verbal learning and executive dysfunction. Therefore, feasibility of EMDR-treatment to improve cognitive performance in older adults with PTSD was examined. Additionally, we investigated pre-treatment correlation with often co-occurring risk factors for cognitive decline (sleep problems,...

Samenvatting We zagen een 73-jarige vrouw met een recidiefdepressie en gegeneraliseerde angststoornis. Zeven weken gele-den was hiervoor escitalopram door de huisarts gestart. Het middel bleek niet effectief en werd afgebouwd met als doel een ander antidepressivum te starten. Tijdens de afbouw was er sprake van acute geheugenproblematiek geduid als...

Background: Psychiatric comorbidity is high in adults with posttraumatic stress disorder (PTSD), with up to 90% having at least one additional condition, and two-thirds having two or more other diagnoses. With an increasing aging population in industrialized counties, knowing which psychiatric disorders frequently co-occur in older adults with PTS...

We investigated whether the impact of potentially traumatic events (PTEs) on trauma-related symptoms changes across the transitional adult lifespan (i.e., 16-100 years old) and if this association differs for self-reported COVID-19-related PTEs compared to other PTEs. A web-based cross-sectional study was conducted among 7,034 participants from 88...

Post-traumatic stress disorder (PTSD) is associated with cognitive dysfunctions and is an independent risk factor for dementia. A recent study has found the prevalence of PTSD in people with dementia is 4.7%-7.8%. However, little is known about the effectiveness of PTSD treatment for people with dementia. The primary aim of the current study is to...

Objectives: Posttraumatic stress disorder is frequently present in people with dementia, but the symptoms are difficult to recognize and suitable treatments are lacking. The aim of the present study was to investigate which trauma-focused treatments are applicable to these patients. Methods: The Delphi method is a process which is used to reach...

We saw a 73-year-old woman, diagnosed with a recurrent depression and generalized anxiety disorder. Escitalopram had been started by her general practitioner more than seven weeks ago. It was not effective, and was therefore tapered with the aim of starting a different antidepressant. During tapering acute memory problems occurred, presumed to be a...

Objective: The aim of this study is to investigate the feasibility of eye movement desensitization and reprocessing (EMDR) therapy in older adults with posttraumatic stress disorder (PTSD), and to explicitly include information about presence of the comorbid psychiatric and somatic disorders as well as a history of traumatic events at treatment st...

Angst- en stemmingsstoornissen komen bij ouderen veelvuldig voor. Van de stemmingsstoornissen komt depressie het meest voor. Bij ouderen komen de depressieve en angstsymptomen vaak minder in aantal, ofwel subsyndromaal, voor, terwijl er dan toch sprake is van een hoge lijdensdruk met grote gevolgen voor het functioneren. Gezien de klinische relevan...

Background: The impact of the COVID-19 pandemic on mental health has been widely reported. Yet, little remains known about the psychological mechanisms associated with changes in mental well-being during the currently ongoing pandemic. Methods: Here, we use a network analysis to unravel complex relationships between COVID-19 related stressors and e...

Objectives Posttraumatic stress disorder (PTSD) after exposure to multiple (childhood) trauma’s is strongly associated with accelerated aging and high psychiatric and somatic comorbidity, influencing frailty and Quality of Life (QoL) in older adults. Eye Movement Desensitization therapy (EMDR) addresses psychological and physiologic symptoms stemmi...

Cognitive and behavioral aspects may mask posttraumatic stress disorder (PTSD) in people with dementia. PTSD severely lowers quality of life in people with dementia. Proper recognition of PTSD is essential to ensure adequate treatment. However, a valid diagnostic tool for PTSD in dementia is lacking. A Delphi study was conducted among 20 Dutch and...

Introduction: Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed to older adults. In contrast to young subjects, it is unclear whether older adults may be vulnerable to cognitive side effects. Serotonin is involved in cognitive functions (e.g. memory). It is of great importance to examine the effects of SSRIs on memory functio...

Posttraumatic stress disorder (PTSD) is a prevalent disorder worldwide and often co‐occurs in dementia. Both have a major impact on disease burden and quality of life. PTSD may be difficult to recognize in dementia and a structured diagnostic method is lacking. In order to get insight into the clinical diagnostics of PTSD in dementia, this systemat...

Background Geriatric psychiatry is still a relatively young field, but it has made itself indispensable in recent years. This article examines specific features of psychopathology in older adults. Aim To examine what makes older adults ‘different’ compared to younger cohorts. Method Non-systematic literature search. Results Older adults are charact...

Background: The mental health impact of the COVID-19 crisis may differ from previously studied stressful events in terms of psychological reactions, specific risk factors, and symptom severity across geographic regions worldwide.

Objective: To examine the treatment outcome of an intensive trauma-focused treatment program for post-traumatic stress disorder (PTSD) in older and younger adults. Methods: A non-randomized outcome study was conducted with 62 consecutively admitted older PTSD patients (60-78 years) and 62 younger PTSD patients (19-58 years), matched on gender an...

Background: Post Traumatic Stress Disorder (PTSD) has been described as an independent risk factor for cognitive decline and dementia. At the same time, cognitive deterioration and increased loss experiences in dementia may increase liability for the reactivation of traumatic memories and thereby PTSD symptoms. Objective: In order to investigate co...

Objective: International guidelines on symptom-based treatment of borderline personality disorders (BPD) in older adults are lacking. The number of older adults (≥ 65 years) with borderline personality disorder is rising. Effectiveness of Selective Serotonin Reuptake Inhibitors (SSRIs) on symptoms of BPD has only been investigated in younger adult...

Pharmacotherapy in older adults with personality disorders is very complicated. On the one hand, this is caused by interference of the personality disorder in the therapeutic relationship. On the other hand, age specific factors, such as polypharmacy and changing pharmacokinetics and -dynamics play an important complicating role. In this article th...

Background: Pharmacotherapy in older adults with personality disorders (PD) is a new and important area of attention. Nowadays, symptom based pharmacotherapy in older adults with PD is based on multidisciplinary guidelines, which are constructed on research performed in patients up to 50 years of age. There is no specific guideline for older adult...

Purpose of Review To provide an update of a life span perspective on borderline personality disorder (BPD). We address the life span course of BPD, and discuss possible implications for assessment, treatment, and research. Recent Findings BPD first manifests itself in adolescence and can be distinguished reliably from normal adolescent development...

Traumatic life events can result in severe psychiatric conditions among which posttraumatic stress disorder (PTSD) is the most prevalent. Due to high comorbidity with other psychiatric diagnoses, PTSD treatment is challenging. In older adults, the presentation of PTSD symptoms is especially complicated because of even higher comorbidity, higher rat...

Recognition of posttraumatic stress disorder (PTSD) in older adults is often difficult due to its complicated presentation. Once recognized, trauma symptoms can, in accordance with (inter)national guidelines, be successfully treated with eye movement desensitization and reprocessing (EMDR) therapy. However, limited empirical research has been done...

Eye Movement Desensitization and Reprocessing (EMDR) is a kind of psychotherapy, which is growing in popularity, particularly for treatment of post-traumatic stress disorder (PTSD). When Shapiro first introduced EMDR in 1989, it was approached as a controversial treatment because of lack of evidence. However, nowadays there is growing evidence for...

Attention deficit hyperactivity disorder (ADHD) may persist into old age with prevalence rates up to 4.4%. We present a case report of an 80-year old man with ADHD complicated by personality pathology and a mild impairment in some executive functions. We illustrate that ADHD in older adults may be misdiagnosed for a neurodegenerative disease or per...

Posttraumatic stress disorder (PTSD) is a mental disorder that is known to have deleterious psychological, physical, and social impacts on individuals. Recognition of PTSD in older adults is difficult due to the complicated presentation taking into account that PTSD symptoms may be masked by other psychiatric and/or somatic diagnoses that are more...

Rationale: Acute Tryptophan Depletion (ATD) is a specific serotonergic challenge tool. Central serotonergic effects of different ATD procedures are possibly not those that are usually assumed. Objectives: In this paper we review data of ATD in an experimental fear model to investigate whether and how methodological differences may affect fear ou...

Er is weinig empirisch onderzoek naar posttraumatische stress stoornis en ouderen. Wat zijn de hobbels om te nemen gedacht vanuit de klinische praktijk? Actuele literatuur wordt gekoppeld aan een gevalsbeschrijving met suggesties voor verder onderzoek.

Acute tryptophan depletion (ATD) studies have shown that serotonin plays a role in learning and memory processes. In this study, we performed a pooled analysis of nine ATD studies in order to examine the nature of the memory-impairing effects of ATD and mediating factors, such as gender, age and vulnerability for disease in which disturbed serotoni...

Serotonin (5-HT) is an important neurotransmitter involved in the brain-gut axis. It is possible to lower the 5-HT level in the body by means of a nutritional intervention using an amino acid mixture; the acute tryptophan depletion (ATD) method. We studied the effect of ATD on gastric emptying in healthy females, who received both ATD and placebo i...

Lower serum high-density lipoprotein cholesterol and increased ratio of omega-6/omega-3 fatty acids have been reported in unipolar and bipolar depressed patients. Changes in cholesterol and fatty acids have been suggested to affect membrane viscosity and consequently serotonergic neurotransmitter expression. The goal of this study was to investigat...

Cognitive impairment has repeatedly been described in bipolar disorders (BD). Serotonin (5-hydroxytryptophan; 5-HT) is possibly involved in these cognitive processes, more particularly in executive functions, learning, memory, and attention. The aim of this study was to investigate serotonergic vulnerability and its relation to cognitive functionin...

The interest in the function of the serotonergic system in relation to cognition stems from three sources: (1) the association of depression, cognitive dysfunction and 5-HT dysregulation; (2) the association of drug-induced 5-HT dysregulation and cognitive dysfunction; and (3) the association of cognitive performance and serotonergic function per s...

Serotonin (5-hydroxytryptamine; 5-HT) and endocrine abnormalities have been repeatedly reported in bipolar disorders (BD). Useful methods to investigate 5-HT responsivity, and the interaction with neuroendocrine functioning, are provided by acute 5-HT challenge and depletion paradigms. In this review 5-HT challenges are limited to paradigms that st...

Biological vulnerability for bipolar disorders (BD) in relatives of BD patients has not as yet been established. Serotonergic vulnerability was studied, using acute tryptophan depletion (ATD), in healthy first-degree relatives of BD patients and healthy controls. The effects of ATD on mood and cortisol release in 30 healthy adult, lifetime symptom...

Central serotonergic vulnerability indicated by altered mood and neuroendocrine responses to an intravenous (i.v.) tryptophan (Trp) challenge was assessed in healthy adult unaffected first-degree relatives of bipolar disorder (BD) patients (n = 30) (family history; FH). The effects of a single dose of 7.0 g Trp on mood, cortisol and prolactin (Prl)...

Objectives: In the present paper the association of stress-induced cortisol with memory impairment is discussed Methods: An experiment is described in which an attempt is made to block stress-induced cortisol by lowering 5-HT neurotransmission by means of acute tryptophan depletion (ATD). Forty-five healthy control subjects participated in the expe...

Serotonergic circuits have been proposed to mediate cognitive processes, particularly learning and memory. Cognitive impairment is often seen in bipolar disorders in relation to a possible lowered serotonergic turnover. We investigated the effects of acute tryptophan depletion (ATD) on cognitive performance in healthy first-degree relatives of bipo...

Serotonin (5-HT) has been implicated in the pathophysiology of bipotar disorders. Acute tryptophan depletion (ATD), which decreases serotonergic turnover, is an established paradigm to study serotonergic vulnerability in affective disorders. Literature on the application of ATD as a research tool in bipolar patients is limited to three studies, whi...

Animal and human studies have provided evidence for serotonergic modulation of cognitive processes. However, the exact nature of this relationship is not clear. We used the acute tryptophan depletion (ATD) method to investigate the effects of lowered serotonin synthesis on cognitive functions in 17 healthy young volunteers. The study was conducted...
