Psychosis in elderly

Sarah D Holder, Alaina L Edmunds, Sherri Morgan
Antipsychotic drugs block dopamine receptors and are used to manage psychosis as well as other mental illnesses that may or may not have psychotic features, such as bipolar disorders and major depressive disorder. First-generation antipsychotic drugs are more likely to cause adverse effects such as extrapyramidal symptoms and tardive dyskinesia. Adverse effects of second-generation antipsychotic drugs typically are related to metabolic abnormalities such as weight gain, abnormal blood glucose levels, and elevated lipid levels...

Psychosis is one of the most common conditions in later life, with dementia being a main contributing factor. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), now categorizes the various types of dementia as neurocognitive disorders. Alzheimer disease is a common cause of dementia and psychosis. Psychosis also is seen in patients with vascular dementia and dementia with Lewy bodies. Psychosis can be primary, caused by a psychiatric disorder listed in the DSM-5, or secondary, due to a medical or neurologic condition...

Citalopram, mirtazapine and risperidone are frequently prescribed for psychiatric illnesses such as depression and psychosis or for aggressive behavior in elderly patients with dementia. The plasma concentrations vary greatly between patients, especially in elderly patients. Thus, therapeutic drug monitoring (TDM) increases the safety of antipsychotic treatment and a more rapid response to treatment may be achieved. To facilitate TDM, the objectives of this study were to develop and validate a reliable dried blood spot method to simultaneously quantify citalopram, mirtazapine and risperidone including its active metabolite 9-hydroxyrisperidone...

The aim of our study was to assess psychotic-like experiences in the general population aged 18-30 years old of the city of São Paulo, Brazil. A household survey was conducted with 1950 young-adults randomly drawn from the city's general population. The validated 92-item Portuguese version of the Prodromal Questionnaire (PQ) was used for face-to-face interviews. Latent class analysis was conducted. Mean age was of 24 years; 51.1% of the sample was of women. Mean total score on the PQ was 22.06 (SD=17.16). Considering a suggested cut-off of 14 in the positive subscale, 30...

Parkinson's disease (PD) has a prevalence of nearly 1 million people in the USA, with increasing incidence in the elderly population. Generally, the age of presentation is between 55 and 65 years, with the likelihood of diagnosis increasing as patients reach the age of 80 years or above. Some of the common treatments for PD increase dopamine levels in the brain. Dopaminergic therapy helps to improve motor and non-motor symptoms, but it is not without risks. Dopaminergic therapy can cause confusion, delirium, and psychotic-like behavior...

We describe the case of an elderly woman with elderly-onset rheumatoid arthritis, where the use of 4 mg/kg/day of hydroxychloroquine (HCQ) was followed by the onset of psychomotor agitation with marked physical and verbal violence towards her partner, including throwing objects at her partner. No disturbance in sleep and no anxiety, nervousness, or irritability had emerged before the onset of her psychomotor agitation. The disappearance of agitation following targeted pharmacologic intervention and HCQ interruption, its re-onset after reintroduction of the drug, and the high score (9) of Naranjo's algorithm are surely linked to the existence of a causal relationship between HCQ and psychomotor agitation...

Epileptic emergencies are frequently encountered and include ictal events as status epilepticus or seizure clusters, and non-ictal situations like postictal psychosis or acute drug side effects. The aim of this review was to describe recent pharmacological advances in the treatment of epileptic emergencies. Areas covered: Based on clinically relevant questions, a literature search was performed. The search showed that most pharmacological advances have been made in management of status epilepticus, where substantial literature has accumulated on several AEDs with potentially less side-effects than the traditional choices...

We present the case of an elderly woman with hypothyroidism and no psychiatric history who presented with new onset of psychosis, paranoia, catatonic features and Capgras syndrome (CS). This case illustrates the spectrum of neuropsychiatric symptoms that may accompany hypothyroidism and the importance of considering thyroid dysfunction as a primary contributor to severe psychiatric symptoms, especially in previously stable patients. We demonstrate the effectiveness of combination levothyroxine and olanzapine, with its favourable cardiac profile, in the treatment of myxoedema madness...

IMPORTANCE: Chronic opioid use imposes a substantial burden in terms of morbidity and economic costs. Whether opioid-naive patients undergoing surgery are at increased risk for chronic opioid use is unknown, as are the potential risk factors for chronic opioid use following surgery. OBJECTIVE: To characterize the risk of chronic opioid use among opioid-naive patients following 1 of 11 surgical procedures compared with nonsurgical patients. DESIGN, SETTING, AND PARTICIPANTS: Retrospective analysis of administrative health claims to determine the association between chronic opioid use and surgery among privately insured patients between January 1, 2001, and December 31, 2013...

OBJECTIVE: To investigate the incidence of serious adverse events (SAE) of subthalamic deep brain stimulation (STN-DBS) in elderly patients with Parkinson's disease (PD). METHODS: We investigated a group of 26 patients with PD who underwent STN-DBS at mean age 63.2 ± 3.3 years. The operated patients from the EARLYSTIM study (mean age 52.9 ± 6.6) were used as a comparison group. Incidences of SAE were compared between these groups. RESULTS: A higher incidence of psychosis and hallucinations was found in these elderly patients compared to the younger patients in the EARLYSTIM study (p < 0...

The authors set out to examine qualitatively the use of antiepileptic drugs (AEDs) in a population of older adults in a nursing home setting, evaluating aspects such as specialist prescriptions and changes in dosage. This retrospective prevalence study was carried out in a state-funded nursing home that provides care and rehabilitation for elderly people. The first objective of the study was to determine the prevalence of AED use in this population. The second objective was to monitor AED dosage modifications during the fifteen-month study period, focusing on the safety and the tolerability of AEDs...

This series of columns has 3 main goals: (1) to explain class warnings as used by the United States Food and Drug Administration, (2) to increase awareness of movement disorders that may occur in patients treated with antipsychotic medications, and (3) to understand why clinicians should refrain from immediately assuming a diagnosis of tardive dyskinesia/dystonia (TD) in patients who develop abnormal movements during treatment with antipsychotics. The first column in the series presented a patient who developed abnormal movements while being treated with aripiprazole as an augmentation strategy for major depressive disorder (MDD) and reviewed data concerning the historical background, incidence, prevalence, and risk factors for tardive and spontaneous dyskinesias, the clinical presentations of which closely resemble each other...

Behavioral and psychological symptoms of dementia (BPSD) include apathy, sleep problems, irritability, wandering, elation, agitation/aggression, and mood disorders such as depression and/or anxiety. Elderly patients are usually treated with second-generation antipsychotics; however, they present not enough efficacy against all symptoms observed. Hence, there still is an unmet need for novel pharmacotherapeutic agents targeted BPSD. A novel arylsulfonamide derivative ADN-1184 has been developed that possesses a preclinical profile of activity corresponding to criteria required for treatment of both psychosis and depressive symptoms of BPSD without exacerbating cognitive impairment or inducing motor disturbances...

High total homocysteine (tHcy) is associated with cognitive impairment in the elderly. The impact of high tHcy on different cognitive domains deserves further investigation, as does the role of the C677T polymorphism of the 5,10 methylenetetrahydrofolate reductase (MTHFR) gene. A cross-sectional analysis of 903 subjects from the population-based "InveCe.Ab" study was performed. The participants had no psychosis or active neurological disorders. They underwent a neuropsychological assessment. Principal component analysis allowed cognitive performance to be condensed into two components: executive functions and memory...

Pimavanserin (ACP-103) is a selective inverse agonist of the 5-hydroxytryptamine 2A (5-HT2A) receptor intended to treat patients with Parkinson's disease psychosis (PDP). Currently there are no FDA-approved medications in the United States for the treatment of PDP, although on September 2, 2014, the United States Food and Drug Administration granted breakthrough therapy status to pimavanserin, highlighting the unmet need for therapeutics in this class. Most antipsychotic medications worsen motor dysfunction due to dopamine antagonism, and all carry a black box warning for an increased risk of mortality in elderly patients with dementia-related psychosis...
