Multiple system atrophy (MSA), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD) are the most common atypical parkinsonisms. These disorders are characterized by varying combinations of autonomic, cerebellar and pyramidal system, and cognitive dysfunctions. In this paper, we reviewed the evidence available on the presence and type of neuropsychiatric disturbances in MSA, PSP, and CBD. A MedLine, Excerpta Medica, PsycLit, PsycInfo, and Index Medicus search was performed to identify all articles published on this topic between 1965 and 2018.

The use of ecological tests to assess executive functions (EFs) in patients with anorexia nervosa (AN) has not examined extensively. The objective of this study was to analyze and compare the performance of patients with AN and healthy controls (HCs) on standard versus ecologically valid tests on EFs. Sixty-two females aged between 16 and 42 who were diagnosed with AN and 70 matched HCs completed 2 neuropsychological test batteries: standard tests (WCST, TMT, Stroop, ToL, fluency test) and the Behavioral Assessment of Dysexecutive Syndrome (BADS).

Commentary: Cortical plasticity and olfactory function in early blindness

Perseverative cognition represents a prototypical example of how our internal thoughts can impact our psychological and physical health, as if we were facing an actual environmental stressor (Brosschot et al., 2006). The mechanisms involved—together with other emblematic examples like the placebo effect—provide clear evidence for brain-body interaction.

Prenatal exposure to the antiepileptic and mood stabilizer valproic acid (VPA) is an environmental risk factor for autism spectrum disorders (ASD), although recent epidemiological studies show that the public awareness of this association is still limited. Based on the clinical findings, prenatal VPA exposure in rodents is a widely used preclinical model of ASD. However, there is limited information about the precise biochemical mechanisms underlying the link between ASD and VPA.

Results from preclinical rodent studies during the last 20 years implicated glutamate neurotransmission in different
brain regions in drug self-administration and rodent models of relapse. These results, along with evidence for druginduced
neuroadaptations in glutamatergic neurons and receptors, suggested that addiction might be treatable by
medications that inhibit glutamatergic responses to drugs of abuse, drug-associated cues, and stressors. This idea is

The endocannabinoid (eCB) system is highly stress sensitive and known to modulate memory formation of emotionally arousing experiences across different corticolimbic structures. eCB signaling within these circuits is also essentially involved in regulating non-genomically mediated glucocorticoid hormone effects on memory.
