Approximately one-third of stroke survivors develop poststroke depression. Post-stroke mania is relatively rare, with a prevalence of less than 2%. One review of case reports of late-onset mania in 2015 demonstrated that 51% of the patients had established vascular risk factors. In 28% of cases, the treatment of underlying organic cause contributed to successful remission of the manic episode.

For this review, we aimed to compile published case reports from the past 20 years to review late-onset mania as one of the neuropsychiatric outcomes of stroke and its management.

Among the 17 case reports, the age of onset of manic episode ranged from 47 to 86 with a mean of 67 years. Of the 17 cases, the right hemisphere was the most frequently affected (14/17, 82%), with cerebrovascular lesion involving the left hemisphere in 3 cases (17.6%).

Clinicians should consider mania secondary to an organic cause in patients presenting with focal or soft neurological signs or symptoms, manic episode with atypical symptoms such as visual or olfactory hallucinations, altered mental status, disorientation, impairment in memory or cognition, unusual age of onset for bipolar disorder, or unusual illness course such as single episode of mania or poor response to psychopharmacologic treatment. Some reviews suggest combination of mood stabilizers and second-generation antipsychotics. Benzodiazepines recommended as an adjunctive drug for acute management such as agitation, aggressive behavior or disinhibition.

Alzheimer's disease (AD) is considered to be a disorder predominantly affecting memory. It is increasingly recognized that the cognitive profile may be heterogeneous. We hypothesized that it would be possible to define distinct “cognitive phenotypes” in older people with AD.

Participants from three individual studies were included, consisting of 109 patients with a diagnosis of probable AD, and 91 age- and gender-matched control participants. All had demographic and cognitive assessment data available, including the Cambridge Cognitive Examination of the Elderly (CAMCOG). The CAMCOG scores and sub-scores were further analyzed using hierarchical cluster analysis and factor analysis.

Three clusters were identified. The scores loaded onto three factors representing the domains of attention, praxis, calculation, and perception; memory; and language comprehension and executive function. The main difference between the clusters related to degree of memory impairment. The composite score for memory between the clusters remained significantly different despite adjustment for illness duration and age of onset (p < 0.001).

These data suggest clinical heterogeneity within an older group of people with AD. This may have implications for diagnosis, prognosis, response to currently available treatments, and the development of novel therapies.

Tardive Tourette‐like syndrome is recognised by the observation of several motor and vocal tics often in individuals receiving psychotropic medications and can happen within 1–3 months of treatment.

We report a case which is unique in its onset of Tardive Tourette‐like syndrome comprising of vocal, motor tics and coprolalia after more than three decades of treatment with combination depot and oral neuroleptics.

Use of the Naranjo Adverse Drug Reaction Probability Scale indicates a probable relationship between the onset of Tardive Tourettism and the antipsychotic therapy in this patient. This was in contrast to earlier reports which noted earlier onset and partial reversal with termination or change of medications. Clinicians need to pay heed to the emergence of late‐onset Tourettism in order to better manage its manifestation and prevent its worsening in the context of holistic care for patients with neuropsychiatric conditions including schizophrenia.

There is evidence to suggest that cognitive deficits might persist beyond the acute stages of illness in major depressive disorder (MDD). However, the findings are somewhat inconsistent across the individual studies conducted to date. Our aim was to conduct a systematic review and meta-analysis of existing studies that have examined cognition in euthymic MDD patients.

Following a systematic search across several publication databases, meta-analyses were conducted for 27 empirical studies that compared euthymic adult MDD patients (895 participants) and healthy controls (997 participants) across a range of cognitive domains. The influence of demographic variables and confounding factors, including age of onset and recurrent episodes, was examined.

Compared with healthy controls, euthymic MDD patients were characterized by significantly poorer cognitive functions. However, the magnitude of observed deficits, with the exception of inhibitory control, were generally modest when late-onset cases were excuded. Late-onset cases demonstrated significantly more pronounced deficits in verbal memory, speed of information processing and some executive functions.

Cognitive deficits, especially poor response inhibition, are likely to be persistent features, at least of some forms, of adult-onset MDD. More studies are necessary to examine cognitive dysfunction in remitted psychotic, melancholic and bipolar spectrum MDD. Cognitive deficits overall appear to be more common among patients with late-onset depression, supporting the theories suggesting that possible vascular and neurodegenerative factors play a role in a substantial number of these patients.

This study investigates the influence of age at onset of OCS on psychiatric comorbidities, and tries to establish a cut-off point for age at onset.

Three hundred and thirty OCD patients were consecutively recruited and interviewed using the following structured interviews: Yale-Brown Obsessive Compulsive Scale; Yale Global Tic Severity Scale and the Structured Clinical Interview for DSM-IV. Data were analyzed with regression and cluster analysis.

Lower age at onset was associated with a higher probability of having comorbidity with tic, anxiety, somatoform, eating and impulse–control disorders. Longer illness duration was associated with lower chance of having tics. Female gender was associated with anxiety, eating and impulse–control disorders. Tic disorders were associated with anxiety disorders and attention-deficit/hyperactivity disorder. No cut-off age at onset was found to clearly divide the sample in homogeneous subgroups. However, cluster analyses revealed that differences started to emerge at the age of 10 and were more pronounced at the age of 17, suggesting that these were the best cut-off points on this sample.

Age at onset is associated with specific comorbidity patterns in OCD patients. More prominent differences are obtained when analyzing age at onset as an absolute value.
