Cerebral venous thrombosis (CVT) is rare and has a wide spectrum of symptoms, therefore it is difficult to diagnose. Thrombosis of the deep cerebral veins occurs very rarely: it has been reported that approximately 6% of patients with CVT have deep CVT, and the prognosis for patients with this condition is poor. CVT has been reported in association with dehydration, a hypercoagulable state, mastoiditis, tumour invasion of a venous sinus, use of oral contraceptives, pregnancy, puerperium, head trauma, vasculitis, and intracranial and systemic infections. However, in the literature, there are few reported cases of CVT in association with iron deficiency anaemia, especially in adults. We present here two patients with bilateral thalamic and basal ganglionic lesions due to thrombosis of the deep cerebral veins. Both of our patients had severe hypochromic microcytic anaemia due to iron deficiency, and both had a good prognosis after 2 months.

Background: Multifrequency MR elastography (mMRE) enables noninvasive quantification of renal stiffness in patients with chronic kidney disease (CKD). Manual segmentation of the kidneys on mMRE is time-consuming and prone to increased interobserver variability.
Purpose: To evaluate the performance of mMRE combined with automatic segmentation in assessing CKD severity.

EEG involves recording electrical activity generated by the brain through electrodes placed on the scalp. Imagined speech classification has emerged as an essential area of research in brain-computer interfaces (BCIs). Despite significant advances, accurately classifying imagined speech signals remains challenging due to their complex and non-stationary nature.

Purpose: Conventional brain MRI protocols are time-consuming, which can lead to patient discomfort and inefficiency in clinical settings. This study aims to assess the feasibility of using artificial intelligence-assisted compressed sensing (ACS) to reduce brain MRI scan time while maintaining image quality and diagnostic accuracy compared to a conventional imaging protocol.
Patients And Methods: Seventy patients from the department of neurology underwent brain MRI scans using both conventional and ACS protocols, including axial and sagittal T2-weighted fast spin-echo sequences and T2-fluid attenuated inversion recovery (FLAIR) sequence.

Schizophrenia is a heterogeneous neuropsychological disorder characterized by three distinct sets of symptoms: positive, negative, and cognitive. It carries significant public health implications and is estimated to affect up to 1% of the population. Despite extensive research, the underlying mechanisms of schizophrenia are not entirely understood, and existing antipsychotic treatments have notable limitations.

Background: Superagers, older adults with exceptional cognitive abilities, show preserved brain structure compared to typical older adults. We investigated whether superagers have biologically younger brains based on their structural integrity.
Methods: A cohort of 153 older adults (aged 61-93) was recruited, with 63 classified as superagers based on superior episodic memory and 90 as typical older adults, of whom 64 were followed up after two years.
