Patients And Methods: The analysis includes 735 participants (aged 20 to 79 years) without neurological or severe cardiac diseases.

Imaging modalities in neurolisteriosis: a literature review.

Listeriosis caused by due to its ability to withstand harsh conditions and form biofilms on post-processed food poses a serious public health issue. It typically manifests itself with fever and gastrointestinal symptoms, but it can escalate with life-threatening conditions, especially in immunocompromised patients, the elderly, oncologically sick, and even pregnant women. The diagnosis is based on blood and cerebrospinal fluid culture growth, but it presents significant challenges due to deceptive findings and low positivity rates, the golden standard includes molecular diagnostic tests such as real-time PCR and metagenomic next-generation sequencing, which offer higher sensitivity and rapid detection.

Imaging of Lyme Neuroborreliosis: A Pictorial Review.

Lyme neuroborreliosis is a common feature of infection (as a neurological manifestation occurring in 10%-15% of all Lyme disease cases) and may involve any part of the nervous system, and its coverings, but usually manifests as lymphocytic meningitis, cranial neuritis, and/or radiculoneuritis. This review describes the imaging findings in Lyme neuroborreliosis: the focal point is on the manifestations of involvement visible on brain and spine imaging.

Neuronal loss or dysfunction in patients with early Lyme neuroborreliosis: a proton magnetic resonance spectroscopy study of the brain.

Background: We hypothesized that since Borrelia burgdorferi causes systemic inflammation and infects the brain, it may lead to alterations in cerebral metabolism, as measured by H-magnetic resonance spectroscopy (H-MRS). The purpose of our study was to determine whether H-MRS could detect brain metabolite alterations in patients with early Lyme neuroborreliosis (LNB) in normal-appearing brain tissue on the conventional magnetic resonance imaging (MRI).

Methods: Twenty-six patients diagnosed with early LNB and twenty-six healthy volunteers as a control group have been involved in the study.

Proton magnetic resonance spectroscopy (H-MRS) of the brain in patients with tick-borne encephalitis.

Tick-borne encephalitis (TBE) is a disease caused by a tick-borne encephalitis virus (TBEV) belonging to the Flaviviridae family. The aforementioned virus is transmitted by the bite of infected ticks. In the recent years, TBEV has become a serious public health problem with a steady increase in its incidence, mainly due to the climate changes and spreading the infected ticks into new territories.

Evaluation of Imaging Methods in Tick-Borne Encephalitis.

Tick-borne encephalitis (TBE) is caused by a virus that belongs to the family and is transmitted by tick bites. The disease has a biphasic course. Diagnosis is based on laboratory examinations because of non-specific clinical features, which usually entails the detection of specific IgM antibodies in either blood or cerebrospinal fluid that appear in the second phase of the disease.

Duration of untreated psychosis and proton magnetic resonance spectroscopy (1H-MRS) findings in first-episode schizophrenia.

Background: The duration of untreated psychosis (DUP) is a factor associated with the natural course of schizophrenia and an independent predictor of treatment outcome. Recent studies focus on the effects of DUP on the functioning of the nervous system, but the findings are inconsistent. As proton magnetic resonance spectroscopy (1H-MRS) enables the assessment of signals from chemical compounds in vivo, it seems a useful tool to explore this problem.

Background: Epilepsy is a disease which manifests itself with recurrent dysfunction of the brain. Epilepsy thus becomes a serious social problem and it is therefore necessary to introduce more and more up-to-date methods of its diagnostics.

Material/methods: Examinations were performed on 85 patients with partial epileptic attacks.

N-acetylaspartate (NAA) levels in selected areas of the brain in patients with chronic schizophrenia treated with typical and atypical neuroleptics: a proton magnetic resonance spectroscopy (1H MRS) study.

Background: NAA, marker of neurons integrity and viability, is one of the most important brain metabolites visible in 1H MRS. In most studies of schizophrenia, the decrease of NAA level was observed in the temporal, frontal lobes and in the thalamus. This finding was observed more often among chronic patients, what suggests the influence of disease duration or the effect of neuroleptic treatment.
