Article Synopsis
  • - The study investigated the behavioral and psychological symptoms of dementia (BPSD) in patients with Alzheimer’s disease dementia (ADD) and mild cognitive impairment (MCI), focusing on how caregiver relationships affect these symptoms.
  • - Researchers evaluated cognitive function in 419 patients using two tests and found significant connections between caregiver relationships and factors like patient age, education level, and total BPSD scores based on the Neuropsychiatric Inventory Questionnaire (NPI-Q).
  • - Specific symptoms such as delusions and irritability were notably tied to the caregiver’s relationship with the patient, with female caregivers reporting higher scores in certain emotional symptoms, indicating that the caregiver’s role can influence the patient’s psychological state.

Introduction: Dementia is caused by various diseases, including Alzheimer's disease dementia (ADD) and dementia with Lewy bodies (DLB). We often encounter patients with dementia who have limited shoulder joint range of motion (ROM), especially those with behavioral and psychological symptoms of dementia (BPSD). But the relationship between the diseases of dementia and restricted shoulder joint ROM is currently unclear.

The Revised Hasegawa Dementia Scale (HDS-R) is the most widely used instrument to screen for dementia in Japan and is similar to the Mini-Mental State Examination (MMSE). The development of a quicker and simpler screening tool, the Japanese Old Stories Cognitive Scale (JOSS), was previously reported. A total of 953 new outpatients from 8 memory clinics in Japan completed the JOSS, HDS-R, and MMSE at first visit.

Background: In Japan, Alzheimer's disease dementia (AD) is the most common cognitive disease, and the most widely used dementia screening tests are the Revised Hasegawa Dementia Scale (HDS-R) and Mini-Mental State Examination (MMSE). This study sought to elucidate the relationships of the individual domains of these tests with age and duration of school education in a large group of patients with AD.

Methods: Participants were 505 new outpatients diagnosed with AD who completed the HDS-R and MMSE at the first visit.

Background: Alzheimer's disease dementia (ADD) is the most common cognitive disease, but patients' families may notice some symptoms yet not recognise that they indicate ADD. This study investigated the symptoms that families notice as ADD as the disease progresses.

Methods: New outpatients diagnosed with ADD (n = 315) at five memory clinics completed two cognitive assessments, the Revised Hasegawa Dementia Scale (HDS-R) and Mini-Mental State Examination (MMSE).

Some new outpatients with mild cognitive impairment (MCI) or Alzheimer's disease (AD) do not regularly attend treatment appointments at memory clinics. To explore factors related to non-regular attendance, we divided new outpatients according to regular or non-regular attendance during the first 6 months of treatment and analyzed the relationship between individual patient factors and attendance. Approximately half of patients living alone did not regularly attend appointments.

Introduction: Alzheimer's disease (AD) is the most common cognitive disease, and behavioral and psychological symptoms of dementia (BPSD) can place a heavy burden on families. The presence of these symptoms related to AD is commonly assessed using the Neuropsychiatric Inventory Questionnaire (NPI-Q). This study sought to clarify the relationship between scores on the 12-domain NPI-Q and individual factors in patients with AD.

A benzensulfonanilide-type cyclooxygenase-1 (COX-1)-selective inhibitor, ZXX2-77: 4-amino-4'-chloro-N-methylbenzenesulfonanilide (4a), has been reported as a novel analgesic that does not cause gastric damage. This compound has a weak analgesic effect but has potent in vitro COX-1 inhibitory activity. Since the reason for the weak analgesic effect in vivo was thought to be the low rate of oral absorption, the blood concentration of ZXX2-77 (4a) was measured in rats.

Although cyclooxygenase-1 (COX-1) inhibition is thought to be a major mechanism of gastric damage by nonsteroidal anti-inflammatory drugs (NSAIDs), some COX-1-selective inhibitors exhibit strong analgesic effects without causing gastric damage. However, it is not clear whether their analgesic effects are attributable to COX-1-inhibitory activity or other bioactivities. Here, we report that N-(5-amino-2-pyridinyl)-4-(trifluoromethyl)benzamide ( 18f, TFAP), which has a structure clearly different from those of currently available COX-1-selective inhibitors, is a potent COX-1-selective inhibitor (COX-1 IC 50 = 0.
