Two patients, a 38-year-old man and a 32-year-old woman, were admitted to a psychiatric ward. The first patient suffered from a mood disorder, personality changes and complained of several, hitherto unexplained physical symptoms. Finally the patient was diagnosed with paraneoplastic cerebellar degeneration associated with Hodgkin's disease. The second patient presented with psychosis and panic disorders, but the condition was later found to be caused by paraneoplastic limbic encephalitis due to ovarian teratomas. These cases illustrate that patients with paraneoplastic neurological syndromes may present with psychiatric symptoms which can hamper an early diagnosis.

Background: Behavioural and psychological symptoms of dementia (BPSD) can complicate acute hospital care, but evidence on BPSD in this setting is heterogeneous.
Objective: To determine the prevalence of BPSD in acute hospitals and explore related risk factors, treatments, and outcomes (PROSPERO: CRD42023406294).
Methods: We conducted a systematic review and meta-analysis by searching Cochrane Library, MEDLINE, and PsycINFO for studies on BPSD prevalence among older people with dementia during their acute hospital admissions (up to 5 March 2024).
The effect of Lewy body (co-)pathology on the clinical and imaging phenotype of amnestic patients.

Lewy body (LB) pathology is present as a co-pathology in approximately 50% of Alzheimer's disease (AD) dementia patients and may even represent the main neuropathologic substrate in a subset of patients with amnestic impairments. However, the degree to which LB pathology affects the neurodegenerative course and clinical phenotype in amnestic patients is not well understood. Recently developed α-synuclein seed amplification assays (αSyn-SAAs) provide a unique opportunity for further investigating the complex interplay between AD and LB pathology in shaping heterogeneous regional neurodegeneration patterns and clinical trajectories among amnestic patients.

This study aimed to examine early mathematical abilities in young children with autism aged four to seven without intellectual disabilities and their connection with autism severity, non-verbal intelligence, and linguistic abilities (receptive vocabulary and grammar). The study involved 42 children with autism. We assessed participants' cognitive, mathematical, and linguistic abilities.

Purpose: Imaging biomarkers bear great promise for improving the diagnosis and prognosis of cognitive impairment in Parkinson's disease (PD). We compared the ability of three commonly used neuroimaging modalities to detect cortical changes in PD patients with mild cognitive impairment (PD-MCI) and dementia (PDD).
Methods: 53 cognitively normal PD patients (PD-CN), 32 PD-MCI, and 35 PDD underwent concurrent structural MRI (sMRI), diffusion-weighted MRI (dMRI), and [F]FDG PET.
