- Psychiatric diagnoses are not reflections of the aetiology of the disorder, but rather lists of symptoms with considerable overlaps, which hamper research and may cause confusion. The diagnoses of autism spectrum disorder, attention deficit hyperactivity disorder and tic disorder are often comorbid along with a number of other symptomatic syndromes. Individual immune responsivity is possibly involved in pathophysiological mechanisms. Multiple environmental factors may contribute to the clinical phenotypes. Recent research supports to some extent the involvement of dietary and nutritional factors in ADHD. In spite of impressive progress in the molecular biological understanding of the pathophysiology of these disorders, treatment options are still limited and more research is warranted.

- BACKGROUND: Apathy is one of the most prevalent neurobehavioral manifestations in mild cognitive impairment (MCI) and is included among the behavioral and psychological symptoms of dementia (BPSD). Studies suggest that the presence of apathy could be associated with increased dementia risk. The role of apathy in conversion from MCI to dementia, and whether apathy could be a relevant predictor for dementia progression, are still matters of investigation.AIM: To study the relationship between apathy and progression to dementia in individuals with MCI.METHODS: A systematic literature search in Medline, Embase, Cochrane Library, Epistemonikos, PsychINFO, and CINAHL was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search included longitudinal studies reporting on the association between apathy and dementia.RESULTS: The main outcome was pooled unadjusted hazard ratios (HR) of apathy in dementia conversion and included 11 studies with 9504 individuals. There was a significant association between apathy and dementia conversion, HR = 1.54; 95% CI, 1.29, 1.84. Subgroup analysis showed a significant association between apathy and progression to AD.CONCLUSION: Apathy was associated with an increased risk of conversion to AD and all-cause dementia in patients with MCI. The role of apathy as a marker for incident dementia needs to be investigated in large, high-quality studies.

- Background: Emerging evidence suggests that cognitive impairment (CI) and different etiologies of dementia, including Alzheimer's disease (AD), are associated with vascular risk factors and atherosclerosis. In clinical practice, carotid intima-media thickness (CIMT) measured by ultrasonography may be a marker of atherosclerosis. Many studies report increased CIMT in patients with dementia and CI although a firm association has not yet been established.Aim: This systematic review and meta-analysis were conducted to study the relationship between CIMT, dementia, and CI.Methods: The literature search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and included the following databases: Medline, Embase, Cochrane Library, and Epistemonikos. The search spanned from 2000 to 2020 and was limited to English and Scandinavian languages.Results: The main analysis of CIMT in subjects with CI compared to subjects with no cognitive impairment (NCI) included 12 studies; 1,089 subjects with CI and 5,223 with NCI. There was no significant difference in CIMT between the CI and NCI groups. However, subgroup analyses revealed significantly higher CIMT in the mild cognitive impairment (MCI) and dementia groups than the NCI group. In addition, patients with dementia had increased CIMT compared to patients with MCI, and patients with AD demonstrated higher CIMT than those with vascular cognitive impairment (VCI).Conclusion: CIMT may be higher in subjects with CI than in cognitively healthy subjects although no significant difference was observed in our main analysis. CIMT was higher in the dementia group than the MCI group and in the AD group compared to the VCI group.
