Patients with Alzheimer's disease may suffer from noncognitive symptoms as well as cognitive symptoms, which the condition is better known for. Behavioral and psychiatric symptoms are common in patients with Alzheimer's disease and may cause great distress to them and their carers. Symptoms include agitation, aggression, wandering, shouting, depression, apathy and sleep disturbance. The safe and effective management of behavioral and psychiatric symptoms of Alzheimer's disease is one of the greatest challenges clinicians face. Traditionally, pharmacological interventions have been the mainstay of treatment but there is growing evidence for the effectiveness of a wide range of nonpharmacological measures. In this review, the evidence and appropriateness of both types of intervention for behavioral and psychiatric symptoms in Alzheimer's disease are discussed.

In order to clarify the characteristics of Behavioral and Psychological Symptoms of Dementia (BPSD) in patients with mild Alzheimer's disease (AD), BPSD among the severities of Clinical Dementia Rating (CDR) in 74 patients with AD were compared using the Neuropsychiatric inventory (NPI). The result, when compared between mild (CDR = 0.5, 1) and moderate or severe (CDR = 2, 3) AD, was a significant difference in frequency of euphoria, disinhibition and aberrant motor behavior, but no significant difference was found in frequency of delusions, hallucinations, agitation, dysphoria, anxiety, apathy and irritability. In addition, a significant difference was found in the mean scores of the composite score for euphoria, apathy, disinhibition and aberrant motor behavior, but no significant difference was found in the mean scores of the composite score for delusions, hallucinations, agitation, dysphoria, anxiety and irritability. That is, the mild AD groups (CDR 0.5 or 1) had delusions, hallucinations, agitation, dysphoria, anxiety, apathy and irritability as frequently as the moderate or severe AD groups (CDR 2 or 3), and had the equivalent level of composite scores to the moderate or severe AD groups (CDR 2 or 3) in delusion, hallucination, agitation, dysphoria, anxiety and irritability. Therefore, it was supposed that psychotic symptoms (delusion, hallucination) and emotional symptoms (agitation, dysphoria, anxiety, irritability) are important BPSD in patients with mild AD as well as those with moderate or severe AD, and there are needs for health, welfare and medical services for these symptoms.

Noncognitive behavioral and psychiatric disturbances are common in dementia and help in the clinical differentiation of the various subtypes. We studied the frequency of neuropsychiatric disturbances, their relationship to dementia severity and compared these disturbances in Alzheimer's disease (AD), vascular dementia (VaD) and frontotemporal dementia (FTD) using the 12-item Neuropsychiatric Inventory (NPI). A total of 98 patients (AD-44, VaD-31, FTD-23) were evaluated. All subjects were community dwelling at the time of evaluation. The three groups were comparable on global dementia severity and functional ability. All patients had clinically significant scores on the NPI with apathy, irritability and agitation being very common (>90% of patients). AD and VaD patients in Clinical Dementia Rating (CDR) stage 2 had significantly higher scores on the total NPI, agitation and disinhibition subscales compared to those in CDR stage 1. Mean scores in the domains of aberrant motor behavior, disinhibition and appetite/eating behavior differentiated FTD from AD and VaD. Neuropsychiatric disturbances in dementia appear to be universal with agitation, disinhibition and irritability being more frequent in the later stages. In this cohort disinhibition, aberrant motor behavior and appetite/eating disturbances could reliably differentiate AD and VaD from FTD. There were no significant differences between the neuropsychiatric profiles of AD and VaD.

When psychological and behavioral disorders of Alzheimer's disease appear suddenly, somatic, iatrogenic and reactive or relational psychological causes must be ruled out or treated before concluding that the cause is lesional. Non-pharmacological interventions should be privileged for the prevention and management of behavioral manifestations of mild to moderate intensity: psychological support of the patient (short therapies), training the caregiver, work on daily habits, reorganization of the home, behavioral measures against apathy and especially agitation, rehabilitation strategies, and therapy involving music, light, aromas, etc. Pharmacological therapies are only moderately effective in these disorders. They must be targeted and follow a sequence of prescription that maximizes tolerance and distinguishes treatment of acute and chronic states. Anticholinesterase agents may be useful in this domain to prevent or ease some symptoms (especially apathy). The efficacy of memantine must be confirmed by additional data. Some selective serotonin reuptake inhibitors agents may be useful not only in depression but also anxiety, emotional disturbances, irritability and compulsiveness. Atypical neuroleptics are better tolerated than the classic ones. They are most effective in this context but must be reserved for specific indications and limited in time because of the increased risk of stroke. Other psychotropics (benzodiazepines, carbamates, antiepileptics) should be used cautiously in this context.

Levetiracetam (Keppra) is a novel antiepileptic drug approved as adjunctive treatment for adults with partial onset seizures. Although the drug is generally well tolerated, behavioral side effects have been reported in variable frequency. Most behavioral problems are mild in nature (agitation, hostility, anxiety, emotional lability, apathy, depression) and quickly resolve with discontinuation of medication. However, serious psychiatric adverse events may also occur with rare cases of psychosis and suicidal behavior. We report here the case of a 43-year-old woman who developed symptoms compatible with catatonia after being exposed to levetiracetam for the treatment of epilepsy. To our knowledge, it is the first reported case of catatonia induced by levetiracetam. We review the difficulties that may be encountered in the differential diagnosis of medical catatonia.

This study aims to investigate the emotional impact of psychiatric symptoms of patients with dementia on their caregiving partners, and to explore if caregiver, patient, and situation factors predict this emotional impact on caregivers. A cross-sectional design was used. Partners of patients with slight to moderately severe dementia who live in the community (n = 85) were interviewed. In a subgroup (n = 58) potential predictors of emotional impact of psychiatric symptoms on caregivers were studied. Agitation, irritability, apathy, and disinhibition produced the highest mean emotional impact scores in caregivers. Besides the neuropsychiatric symptoms themselves, the emotional impact of these symptoms on caregivers was predicted by sense of competence, degree of care needed by the patient, and financial expenditure due to the caregiving situation. The emotional impact of psychiatric symptoms on caregivers is predicted by several patient, caregiver, and situation factors. Interventions aimed at decreasing the experienced burden of caregivers should therefore not only focus on the psychiatric symptoms of the patient, but also on the sense of competence of the caregiver and the financial burden due to the caregiving situation.

The purpose of this research was to assess the frequency and severity of neuropsychiatric and behavioral symptoms and to examine the association between preexisting medical conditions and specific neuropsychiatric symptoms in demented individuals. We studied 211 demented subjects (87.7 percent male) who were participants in epidemiological studies of dementia. Using the Neuropsychiatric Inventory (NPI), we assessed the frequency and severity of neuropsychiatric symptoms. We collected medical history information during a structured telephone interview. Our analyses focused on determining prevalence of neuropsychiatric symptoms by dementia diagnosis and severity. We also examined the association of history of head injury, alcohol abuse, and stroke with development of neuropsychiatric symptoms. We found that neuropsychiatric symptoms were common, with approximately three-fourths of the subjects exhibiting at least one symptom during the preceding month. Apathy (39.3 percent), agitation (31.8 percent), and aberrant motor behavior (31.1 percent) were the most frequent symptoms. Frequency and severity of symptoms were similar for the all-dementia and Alzheimer's disease-only groups, neuropsychiatric symptoms varied by severity of dementia, but generally not in a consistent ordinal pattern. History of alcohol abuse, head injury, or stroke was associated with presence of specific neuropsychiatric symptoms in dementia. While psychiatric symptoms are common in dementia, they also vary by type and severity of dementia. The finding that certain medical conditions may increase risk for specific types of neuropsychiatric symptoms expands our knowledge of the natural history of dementia and should improve management of dementia in medically ill patients. Our results may also shed light on mechanisms that underlie neuropsychiatric symptoms.

Eight weeks after his return from Mauritius, a 2.5-year-old boy started to show signs of gastrointestinal illness including diarrhoea with frequent ill-smelling stools as well as restlessness, insomnia and apathy. Proglottids excreted with the faeces were diagnosed as Raillietina madagascariensis (Davain, 1870), the tropical rat tapeworm. Treatment with praziquantel (10 mg/kg BW) proved to be efficient.

The behavioral and psychological symptoms of dementia (BPSD) often present major problems for patients and their caregivers. In the past, neurologists paid less attention to such symptoms than to the cognitive symptoms of dementia. This prospective study investigated the prevalence of psychiatric morbidity in a neurology-based memory clinic and the stress of caregivers. Our patients with dementia were found to have a high prevalence of BPSD. The most frequent were anxiety, apathy, and delusion; the most distressing to caregivers were agitation, anxiety, delusion, and sleep disturbance. Using Clinical Dementia Rating (CDR), we compared BPSD between patients with mild dementia and those with moderate dementia. Only hallucinations and agitation were different significantly. Moderate dementia patients experienced these symptoms more frequently. The high prevalence of these symptoms might be explained by the fact that the cognitive symptoms were neglected or no enough information were received by many family members of patients with dementia until their own life quality was interfered and then they began to seek medical help. These symptoms and their effect of caregiver distress can be effectively reduced by pharmacologic and nonpharmacoloic managements, caregiver-focused training and education. They can be better approached by assessing neuropsychiatric symptoms regularly, educating the general population better, and treating these patients earlier.

Behavioural problems in dementia are a burden for patients and caregivers and are often the main reason for admission to a nursing home. Research on the prevalence of behavioural problems is scarce. In this study the prevalence of behavioural problems was estimated in nursing home patients with dementia. In 59 demented patients the Neuropsychiatric Inventory (NPI-NH) and the Cohen-Mansfield Agitation Inventory were used to measure behavioural problems over the last two weeks. Behavioural problems were present in about 85% of the study group. Using the NPI-NH aggression/agitation and apathy were present in almost 40% of the patients. Delusions, hallucinations, depression and anxiety were present in 10-15% of the patients. Using the CMAI cursing/verbal aggression, restlessness, complaining, negativism, and mannerisms were prevalent in 30%-50% of the patients. Larger studies on the prevalence of problem behaviour and possibly influencing factors are necessary.
