A number of online neuroscience databases are available which provide information regarding gene expression, neurons, macroscopic brain structure, and neurological or psychiatric disorders. Some databases contain descriptive and numerical data, some to brain function, others offer access to 'raw' imaging data, such as postmortem brain sections ...
The most common comorbid disorders are depression and anxiety, [16] although cases of depersonalization disorder without symptoms of either do exist. Comorbid obsessive/compulsive behaviors may exist as attempts to deal with depersonalization, such as checking whether symptoms have changed and avoiding behavioral and cognitive factors that ...
