“…As described in Lewy body dementia, idiopathic Parkinson disease with dementia can show hypoperfusion patterns similar to those observed in AD, but basal ganglia hypoperfusion is far more frequent, as is frontal precentral hypoperfusion (Caixeta & Vieira, 2008). Corticobasal degeneration presents as bilateral asymmetrical frontal, parietal and basal ganglia hypoperfusion.…”

“…Also Huntington's disease can show bilateral front temporal hypo perfusion, but it presents later in the progression of the disease, while the first sign is severe bilateral basal ganglia hypo perfusion. Dementia associated with Parkinsonism: As described in Lewy body dementia, idiopathic Parkinson disease with dementia can show hypo perfusion patterns similar to those observed in AD, but basal ganglia hypo perfusion is far more frequent, as is frontal precentral hypo perfusion (Caixeta and Vieira, 2008). Corticobasal degeneration presents as bilateral asymmetrical frontal, parietal and basal ganglia hypo perfusion.…”

Problem statement:The structural and functional neuroimaging have much to contribute to the cognitive neuroscience. Approach: We describe a radiological review of the major dementia syndromes and Mild Cognitive Impairment (MCI), included Alzheimer's disease, Lewy body dementia, Vascular dementia, Front temporal Lobar degeneration, Dementia associated with parkinsonism and other amnesic syndromes. Results: The different syndromes and diseases presenting with dementia have different patterns of brain perfusion abnormalities, it is possible to distinguish them with good specificity with neuroimaging. Conclusion: New imaging techniques carry the hope of revolutionizing the diagnosis of dementia so as to obtain a complete molecular, structural and metabolic characterization, which could be used to improve diagnosis and to stage each patient and follow disease progression and response to treatment. Structural and functional imaging modalities contribute to the diagnosis and understanding of the different dementias.

“…Entretanto, as estimativas de sua prevalência variam de acordo com o objetivo e metodologia do estudo (Chen et al, 2007;Cummings, 1992). Veazey et al (2005) relatam que as taxas de depressão em estudos publicados apresentam variação de 7 a 76%. Identificá-la na DP não é tarefa fácil, já que alguns sintomas de depressão, como cansaço e distúrbios do sono, também podem ser atribuídos exclusivamente à DP, o que acaba contribuindo com alto índice de subdiagnósticos (Ravina et al, 2007) (OMS, 2002).…”

“…Presume-se a morte de ao menos 60% desses neurônios ao aparecerem os primeiros sintomas motores da doença (Lang & Lozano, 1998;Hanna-Pladdy et al, 2013). 2005). Sabe-se, entretanto, que o processo fisiopatológico da DP ultrapassa o sistema dopaminérgico, estando também envolvidos os sistemas de neurotransmissores noradrenérgicos, serotonérgicos e colinérgicos (Leentjens, 2004;Filho et al, 2007).…”

Malak, Ana Lara Soares Blum; Charchat-Fichman, Helenice (Advisor).Parkinson's Disease (PD) is characterized by the occurrence of motor symptoms. However, non motor symptoms such as depression and cognitive impairment are common and should not be ignored. This thesis investigated the frequency of depressive symptoms and their effect on cognition in individuals with PD with mild cognitive impairment (MCI). Forty eight subjects with PD and 44 controls (CG), aged between 50 and 80 years and higher education to four years, all with MCI and undiagnosed depression were studied. The participants underwent clinical evaluation with a neurologist, followed by neuropsychological assessment. Depressive symptoms were measured using the Beck Depression Inventory. Difficulty in work, fatigue and sleep disorders were more frequent symptoms in PD group, whereas the group without PD presented beyond sleep disorders, symptoms of irritability, and decreased libido. The presence of these symptoms was found to be associated with loss of attention combined to episodic memory deficits, especially in recognition tasks of new verbal information. The prevalent depressive symptoms in parkinsonians with MCI can be attributed to PD, complicating the differential diagnosis between these conditions.

Studies aiming the characterization of depression in PD patients with MCI are important once these conditions constitute risk factors for dementia.
