what type of aggressive cancer treatment can cause dementia

Chemo brain can occur during or after chemotherapy treatment. Delirium may occur suddenly during treatment. Delirium usually happens after an identified cause, such as chemotherapy, and it is often reversible. Dementia due to cancer treatment comes on gradually over time and usually after treatment is completed.

How long does it take for dementia to progress?

Rapidly progressive dementias (RPDs) are dementias that progress quickly, typically over the course of weeks to months, but sometimes up to two to three years. RPDs are rare and often difficult to diagnose. Early and accurate diagnosis is very important because many causes of RPDs can be treated.

Autoimmune diseases (conditions that over-activate the immune system) Unusual presentations of more common neurodegenerative diseases (such as Alzheimer’s disease) Prion diseases (rare forms of neurodegenerative disease) Infections. Impaired blood flow to or in the brain. Exposure to toxic substances.

How long does it take for dementia to develop?

Rapidly progressive dementias (RPDs) are neurological conditions that develop subacutely over weeks to months, or rarely acutely over days. In contrast to most dementing conditions that take years to progress to death, RPD can be quickly fatal. It is critical to evaluate the RPD patient without delay, usually in a hospital setting, as they may have a treatable condition. In this review, we discuss a differential diagnostic approach to RPD, emphasizing neurodegenerative, toxic/metabolic, infectious, autoimmune, neoplastic, and other conditions to consider.

What is PCNSL in dementia?

PCNSL is an extranodal form of non-Hodgkin's lymphoma. It typically presents with symptoms of intracranial mass lesions, such as headaches, seizures, and focal neurological deficits, but can present as a rapidly progressive dementia.[121] A diffusely infiltrating PCNSL, sometimes called lymphomatosis cerebri, also occurs.[122] Symptoms of PCNSL include personality changes, irritability, memory loss, lethargy, confusion, disorientation, psychosis, dysphasia, ataxia, gait disorder, and myoclonus. [121-124] CNS lymphoma can mimic CJD. [5, 96, 125] PCNSL accounts for 2-3% of all CNS neoplasms. The vast majority of PCNSL are non-Hodgkin diffuse large B-cell type, but T-cell, Burkitt's and poorly characterized forms also occur.[121, 126] The incidence increased from the mid-1970s to the mid-1980s due to an escalating number of immunocompromised patients from transplants, chemotherapy, and patients with HIV before the era of HAART, but seems to have stabilized over the past decade. [126] We focus here on PCNSL in immunocompetent individuals. PCNSL occurs most commonly in the 6thto 7thdecades, but can occur at any age, with a slight male predominance. [123]. Uveitis or vitreitisis present in about 10% of cases, preceding the tumor sometimes by months, in about 75% of cases; identifying the uveitis or vitreitis may allow earlier diagnosis of the cancer.[127]. In immunocompetent individuals, brain MRI may show isointense to mildly hyperintense T2-weighted signal consistent with mass lesions with minimal to moderate edema, often involving the cerebral hemispheres, basal ganglia, periventricular white matter, or corpus callosum. Lesions may be isolated or multiple and generally show contrast enhancement.[128] When presenting as lymphomatosis cerebri, imaging reveals progressive, diffuse white matter signal abnormality without significant (or any) enhancement or mass effect – likely from a diffusely infiltrative process without interruption of the blood-brain barrier. [122, 123] CSF can show a lymphocytosis, increased protein, and low glucose. Serial CSF cytologic evaluations are typically required to identify the lymphoma.[126] EEG may show symmetric or asymmetric nonspecific diffuse slowing [122, 123]Unfortunately, definitive diagnosis often requires brain biopsy. In cases of ocular involvement, diagnosis can sometimes be made by vitrectomy. When possible, it is important to avoid giving corticosteroids prior to biopsy, as steroids can cause tumor cell necrosis, resulting in temporarily shrinkage of the tumor, but preventing tissue diagnosis.[96, 126] Prognosis is poor with patients surviving only a median of 4 months or less without treatment, 12-18 months with whole-brain radiation therapy (WBRT) alone, however upwards of 40 or more months with a combination of aggressive chemo and radiotherapy. Chemotherapy includes high dose systemic methotrexate. The use of chemotherapy alone versus chemotherapy plus WBRT is controversial. Due to the increased risk of neurotoxicity, WBRT in patients over 60 is not recommended. Neurotoxicity presents as an RPD with dementia, ataxia and incontinence, with median onset just over one year post-WBRT [126, 129]

What are the most common tumors associated with PLE?

The most common tumors associated with PLE are small cell lung cancer (SCLC) ( 75% of cases), germ-cell tumors (ovarian or testicular), thymoma, Hodgkin's lymphoma and breast cancer. [52, 53], while the most common antibodies associated with PLE are anti-Hu (ANNA-1), Anti-Ma2 (also called Anti-Ta; antigen is Ma2), CV2 (Anti-CMRP-5), Yo (PCA-1), and probably anti-neuropil. [52, 54-56] Anti-Hu antibodies are found in 50% of cases of PLE cases with SCLC. Identification of anti-neural antibodies is highly suggestive of an underlying neoplasm. Furthermore, the type of autoantibody may suggest the tumor type rather than the neurological syndrome. [52, 57] Almost one-third of patients with a neurological syndrome and autoantibodies will have more than one auto-antibody.[57, 58] In PLE associated with anti-Ma2 (Ta) antibodies and testicular cancer, about half of patients have dramatic improvement of their neurologic syndrome after treatment of their cancer. [56, 59]. This may be in part due to the ability to remove all the cancer through orchiectomy.[60] Hypothalamic involvement is common in patients with anti-Ma2 antibodies.[56] Antibodies to CRMP-5 (Anti-CV2 or Anti-CRMP-5), a protein in the collapsin response-mediator protein family are often associated with PNDs, including PLE. Peripheral neuropathy (47%) and autonomic neuropathy (31%) are the most common neurological signs. Subacute dementia and cerebellar ataxia each occur in about ¼ of patients, followed by neuromuscular junction disorders (12%), chorea (11%) and cranial neuropathy (17%, including optic neuropathy and loss of taste. Spinal fluid is often inflammatory. Anti-CV2 is most often seen with small-cell lung cancers, followed by thymomas. [61, 62] FLAIR MRI in Anti-CV2 antibody syndrome often shows caudate, anterior putamen with or without medial temporal lobe hyperintensity,[58] although thalamic T2-weighted hyperintensity can also occur (manuscript submitted). The striatal and thalamic involvement can appear similar to findings in CJD, however, unlike CJD the T2-weighted hyperintensity may extend beyond the deep grey nuclei into adjacent white matter and there are no diffusion-weighted abnormalities. Most patients with limbic encephalopathy and thymoma (often anti-CV2 or anti-VGKC antibodies) have significant neurologic improvement following tumor removal and treatment. [63] Table 13.3summarizes some of the major antibodies, with their clinical phenotypes, that are associated with limbic encephalopathy.

What diseases affect the CNS?

Collagen vascular and granulomatous diseases also affect the CNS through mechanisms other than vasculitis. Several of these disorders may cause an encephalopathy or rapidly progressive dementia, including primary angiitis of the CNS (PACNS), polyarteritis nodosa (PAN), sarcoidosis, systemic lupus erythematosus (SLE), Sjögren's syndrome, celiac disease (Sprue), Behçet's disease, and hypereosinophilic syndrome. [83-89] Some authors group these encephalopathies of non-vasculitic origin under the term non-vasculitic autoimmune inflammatory meningoencephalopathies (NAIM); this group includes Hashimoto's and Sjogren's encephalopathies; which almost uniformly have abnormal EEGs and respond to high dose steroids. [90] The heralding features of the disorder may be neurological

Can strokes cause dementia?

Depending on the location, strokes can present as rapidly progressive dementia. Large vessel occlusions as well as thalamic, anterior corpus callosal or multiple diffuse infarcts in particular have all presented as RPDs. [92, 93] Thrombotic thrombocytopenic purpura (TTP) can cause microangiopathic thromboses producing global cerebral ischemia, resulting in an encephalopathy. Hyperviscosity syndromes from blood dyscrasias, such as polycythemia or gammopathies, such as Waldenstrom's Macroglobulinemia can present as rapidly progressive dementias by causing global cerebral microvessel ischemia.

Is Alzheimer's disease a CJD?

Alzheimer's disease (AD ) is rarely rapid, but unusual presentations can be mistaken for CJD.[4] Several cases of AD have been reported in conjunction with angiopathy (CAA) presenting as adult onset RPD. [17-19] Other non-prion neurodegenerative diseases that can also present, albeit rarely, in a more fulminant fashion, include DLB, FTD (particularly the subtype with motor neuron disease, CBD and PSP. Patients with AD typically survive a median of 11.7 (SD ±0.6) years, FTD patients 11 years (SD ±0.9) and PSP/CBD patients 11.8 years (SD ±0.6) [20], and PSP alone 5.6 years [21], from first symptom. More rapid onset and/or progression can occur. [20, 22-25]. In a large German study, out of 413 autopsied suspected cases of CJD 7% had AD and 3% had DLB. Myoclonus and extrapyramidal signs occurred in more than 70% of the DLB and more than 50% of the AD patients. [4] Similarly, in a French pathologic study of 465 suspected CJD patients, the two most frequent non-CJD pathologic diagnoses were AD and DLB.[26]

What are the common issues with dementia?

In this article we’ll tackle the thorny issues of apathy, irritability, agitation, aggression, combativeness, inappropriate behavior, willfulness, and sundowning.

What are the symptoms of dementia?

Irritability, agitation, aggression, combativeness, and inappropriate behavior are common in dementia. Has something ever upset you and you felt like breaking something or hitting someone? What would have happened if the part of the brain that stopped you from acting on those feelings was not working? Because the front part of the brain provides the pause between stimulus and response, when it or its connections are damaged, a person may react without thinking. Vascular dementia frequently damages the connections to and from this part of the brain. Other causes of dementia damage it directly. Because of this damage, a person with dementia may act on their feelings without pausing to think whether the action is appropriate or not. They may steal food or other items. They may gamble excessively or engage in other risky behavior. And they may say or do sexually inappropriate things, use more profanity, or make racists or sexists comments.

Does dementia cause willfulness?

One does not need to have dementia to exhibit willfulness. You’ve likely encountered a child (or stubborn individual or any age) who refuses to do something which obviously needs to be done, such as change their clothes after a urinary accident.

Can dementia cause safety issues?

Behavior problems can also lead to safety issues. Dementia may lead individuals to act precipitously without thinking of the consequences. If they are feeling angry, they could strike out with their fists or any available item, including knives, guns, and baseball bats.

Can pencil and paper test detect dementia?

In healthy individuals, the difference is typically small, such that only pencil and paper testing can detect the subtle changes. In an individual whose brain is impaired by dementia, the decline in cognition is often marked, and behavioral changes are usually prominent as well.

Is willfulness common in dementia?

Willfulness is common once dementia reaches the moderate to severe stage. Individuals may be happy and content but suddenly become obstinate when asked to do something they don’t want to—even when is reasonable or necessary. He’s good in the morning, fine at lunch, confused in the afternoon, and a terror in the evening.

How many people can you give a dementia patient a shower?

Rather than having two or three people go to help you give someone a shower, use one person if at all possible. More than one person approaching someone with dementia can raise anxieties and trigger aggression.

Why is dementia important for caregivers?

Because dementia affects communication, the ability to understand what someone else is saying or doing is reduced. As a caregiver, you may mean only to be helpful, but the person with dementia might not understand why you're trying to help her or feel that you're trying to boss her around.

What are the characteristics of dementia?

Characteristic Behaviors. When persons with dementia become angry, they may raise their voice, throw things, display combative behavior such as hitting, kicking, or pushing, yell and scream at you or even try to physically attack you.

How does dementia affect the brain?

Dementia affects the brain, and the brain is responsible for more than just our memory and thought process. The brain also controls our emotions and behaviors. So, depending on where the damage in the brain is, emotions may be affected as well.

Why is anger the hardest to deal with?

This "no-warning" anger can be the hardest to cope with because of its unpredictability. Anger and aggression are the most likely to develop in the middle stages of dementia, along with other challenging behaviors such as wandering, hoarding, and obsessive-compulsive behaviors. 2 .
