This review explores the transformative potential of nanotechnology in the treatment and diagnosis of amyotrophic lateral sclerosis (ALS), a progressive neurodegenerative disorder characterized by motor neuron degeneration, muscle weakness, and eventual paralysis. Nanotechnology offers innovative solutions across various domains, including targeted drug delivery, neuroprotection, gene therapy and editing, biomarker detection, advanced imaging techniques, and tissue engineering. By enhancing the precision and efficacy of therapeutic interventions, nanotechnology facilitates key advancements such as crossing the blood-brain barrier, targeting specific cell types, achieving sustained therapeutic release, and enabling combination therapies tailored to the complex pathophysiology of ALS.

Depression, characterized by persistent sadness, hopelessness and a lack of interest in previously enjoyed activities, is one of the most common mental health disorders. Recent estimates by the World Health Organization (WHO) suggest that approximately 5% of the global population suffers from depression.

For decades, researchers have been trying to devise safe and effective treatments for that cause minimal or no side effects. This led to the introduction of a wide range of strategies, ranging from psychotherapy and to a wide range of pharmacological drugs, including (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), monoamine oxidase inhibitors (MAOIs) and atypical antidepressants.

Most people diagnosed with depression eventually find a suitable treatment for them via a trial-and-error process, ultimately leading to their recovery. Some individuals, however, can experience for prolonged periods of time, finding that no treatment ultimately eases their symptoms.

Dopamine, a small molecule derived from the amino acid tyrosine, plays a significant role in regulating multiple essential brain functions, including movement, mood and motivation as well as multiple cognitive functions, including attention and memory.

Dopamine signaling in the brain is a complex process, with many mechanisms in place to accelerate or slow down dopamine’s effects. When dopamine is released from nerve cells, its efficient removal to limit signaling occurs through the activity of special proteins called “transporters,” ensuring a shorter action of dopamine in the brain.

Disruptions in have been linked to several , including ADHD, schizophrenia, , , and addiction.

Purpose Breast cancer (BC) is one of the most common primary tumor entities that develop brain metastases (BM) during disease progression. Multiple BM are associated with poorer prognosis, but various surgical, radiotherapeutic and systemic treatment approaches improve survival. We aimed to identify prognostic factors and evaluate the overall survival following BM surgery in patients with multiple BCBM. Methods All metachronous metastasized female patients with resected BCBM at our institution between 2008 and 2019 were included. Data on clinical, radiologic, and histopathologic parameters were recorded and analyzed using univariate and multivariate regression models. Results Among the 93 patients included in the final analysis, 30 individuals presented with multiple BM. Compared to patients with single BM, those with multiple BM were more likely to have infratentorial BM (adjusted odds ratio [aOR] 3.35, 95% confidence interval [CI] 1.03–10.83, p = 0.044), HER2(human epidermal growth factor receptor 2)-positive BC (aOR 3.93, 95% CI 1.23–12.53, p = 0.021) and hepatic metastases (aOR 5.86, 95% CI 1.34–25.61, p = 0.019). There was no significant difference in postoperative survival between individuals with multiple (median: 12.5 months) and single BM (17.0 months, p = 0.186). In the multivariate Cox regression analysis, adjuvant radiotherapy (adjusted hazard ratio [aHR] 5.93, 95% CI 1.06–33.26, p = 0.043) and trastuzumab treatment (aHR 4.95, 95% CI 1.72–14.25, p = 0.003) were associated with longer postoperative survival multiple BCBM patients. Conclusion BC patients with multiple BM show remarkable postoperative survival, particularly if combined with adjuvant radiotherapy. Our data justify the surgery of multiple BCBM in patients with appropriate clinical condition and feasible location of BM.

The United States on Friday approved the first blood test for Alzheimer’s, a move that could help patients begin treatment earlier with newly approved drugs that slow the progression of the devastating neurological disease.

The test, developed by Fujirebio Diagnostics, measures the ratio of two proteins in the blood. The ratio is correlated with amyloid plaques in the brain—a hallmark of Alzheimer’s that, until now, has been detected only through brain scans or spinal fluid analysis.

“Alzheimer’s disease impacts too many people—more than breast cancer and prostate cancer combined,” said Food and Drug Administration Commissioner Marty Makary.

A dual-target CAR T cell therapy approach shows promise for slowing tumor growth in a notoriously aggressive and fast-growing brain cancer. Tumors became smaller after the experimental CAR T cell therapy in nearly two-thirds of patients.

While survival data is still accumulating, several patients lived 12 months or longer after receiving the investigational therapy, which is notable given the typical survival for this patient population is less than a year.

The findings were presented at the 2025 American Society of Clinical Oncology (ASCO) annual meeting (Abstract 102) and published in Nature Medicine by researchers from the Abramson Cancer Center (ACC) of the University of Pennsylvania and Penn’s Perelman School of Medicine.
