Author and Disclosure Information

Caring for aggressive patients with dementia can lead to exhaustion, fear, and burnout. These strategies can help improve the welfare of both caregivers and patients.

PRACTICE RECOMMENDATIONS

› Screen caregivers and family members of patients with dementia for signs of interpersonal violence. C

› Counsel caregivers early on that behavior changes in patients with dementia are likely and may be unpredictable. C

› Discuss safety strategies for the caregiver, including when it is appropriate to alter routines such as bedtimes and meals. C

Strength of recommendation (SOR)

A Good-quality patient-oriented evidence
B Inconsistent or limited-quality patient-oriented evidence
C Consensus, usual practice, opinion, disease-oriented evidence, case series

The number of people with dementia globally is expected to reach 74.7 million by 2030 and 131.5 million by 2050.1 Because dementia is progressive, many patients will exhibit severe symptoms termed behavioral crises. Deteriorating interpersonal conduct and escalating antisocial acts result in an acquired sociopathy.2 Increasing cognitive impairment causes these patients to misunderstand intimate care and perceive it as a threat, often resulting in outbursts of violence against their caregivers.3

Available studies (TABLE4-17) make evident the incidence of interpersonal violence experienced by caregivers secondary to aggressive acts by patients with dementia. This violence ranges from verbal abuse, including racial slurs, to physical abuse—sometimes resulting in significant physical injury. Aggressive behavior by patients with dementia, resulting in violence towards their caregivers or partners, stems from progressive cognitive decline, which can make optimal care difficult. Such episodes may also impair the psychological and physical well-being of caregivers, increasing their risk of depression, anxiety, and even post-traumatic stress disorder (PTSD).18 The extent of the impact is also determined by the interpretation of the abuse by the caregivers themselves. One study suggested that the perception of aggressive or violent behavior as “normal” by a caregiver reduced the overall negative effect of the interactions.7Our review emphasizes the unintended burden that can fall to caregivers of patients with dementia. We also address the role of primary care providers (PCPs) in identifying these instances of violence and intervening appropriately by providing safety strategies, education, resources, and support.

Dementia and aggression: A look at the literature

CASE

A 67-year-old man with a medical history of PTSD with depression, type 2 diabetes, alcohol use disorder/dependence, hypertension, and obstructive sleep apnea was brought to his PCP by his wife. She said he had recently been unable to keep appointment times, pay bills, or take his usual medications, venlafaxine and bupropion. She also said his PTSD symptoms had worsened. He was sleeping 12 to 14 hours per day and was increasingly irritable. The patient denied any concerns or changes in his behavior.

Caregivers may refuse support due to personal beliefs or values, accessibility or affordability issues, or in deference to the patient’s wishes.

The PCP administered a Saint Louis University Mental Status (SLUMS) examination to screen for cognitive impairment.19 The patient scored 14/30 (less than 20 is indicative of dementia). He was unable to complete a simple math problem, recall any items from a list of 5, count in reverse, draw a clock correctly, or recall a full story. Throughout the exam, the patient demonstrated minimal effort and was often only able to complete a task after further prompting by the examiner.

A computed tomography scan of the head revealed no signs of hemorrhage or damage. Thyroid-stimulating hormone levels and vitamin B12 levels were normal. A rapid plasma reagin test result was negative. The patient was given a diagnosis of Alzheimer disease. Donepezil was added to the patient’s medications, starting at 5 mg and then increased to 10 mg. His wife began to assist him with his tasks of daily living. His mood improved, and his wife noted he began to remember his appointments and take his medications with assistance.

However, the patient’s irritability continued to escalate. He grew paranoid and accused his wife of mismanaging their money. This pattern steadily worsened over the course of 6 months. The situation escalated until one day the patient’s wife called a mental health hotline reporting that her husband was holding her hostage and threatening to kill her with a gun. He told her, “I can do something to you, and they won’t even find a fingernail. It doesn’t have to be with a gun either.” She was counseled to try to stay calm to avoid aggravating the situation and to go to a safe place and stay there until help arrived.

His memory had worsened to the point that he could not recall any events from the previous 2 years. He was paranoid about anyone entering his home and would not allow his deteriorating roof to be repaired or his yard to be maintained. He did not shower for weeks at a time. He slept holding a rifle and accused his wife of embezzlement.
