Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements include those of the company and its subsidiaries, Cerevel Therapeutics, Inc., Cerevel Therapeutics, LLC and Cerevel MA Securities Corp., after elimination of all intercompany accounts and transactions. The accompanying unaudited condensed consolidated financial statements and notes hereto have been prepared in conformity with the rules and regulations of the Securities and Exchange Commission (SEC) for interim financial reporting and, therefore, omit or condense certain footnotes and other information normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) as set forth in the Financial Accounting Standards Board’s (FASB) accounting standards codification. Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification (ASC) and Accounting Standards Update (ASU) of the FASB. In the opinion of management, all adjustments necessary for a fair statement of the financial information, which are of a normal and recurring nature, have been made for the interim periods reported. Results of operations for the three and six months ended June 30, 2022 and 2021, are not necessarily indicative of the results for the entire fiscal year or any other period. The unaudited condensed consolidated financial statements for the three and six months ended June 30, 2022 and 2021, have been prepared on the same basis as and should be read in conjunction with our audited consolidated financial statements and notes included in our Annual Report.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires us to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions made in the accompanying condensed consolidated financial statements include, but are not limited to, the fair value of our financing liabilities, the fair value of stock options, the accrual for research and development expense and the recoverability of our net deferred tax assets and the related valuation allowance. The impact on accounting estimates and judgments on our financial condition and results of operations due to COVID-19 may introduce additional uncertainties. We evaluate our estimates and assumptions on an ongoing basis using historical experience and other factors and adjust those estimates and assumptions when facts and circumstances change. Actual results could differ materially from those estimates.
Restricted Cash	Restricted Cash In connection with our entering into the lease agreement for our headquarters in Cambridge, MA, in July 2019, we were required to provide a security deposit in the form of a letter of credit. We have classified this amount as restricted cash within our condensed consolidated balance sheets as of June 30, 2022 and December 31, 2021. For additional information related to our other significant accounting policies, please read Note 4, Summary of Significant Accounting Policies, to our audited consolidated financial statements included in our Annual Report.
Recent Accounting Guidance	Recent Accounting Guidance From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the company as of the specified effective date. Unless otherwise discussed, the company believes that the impact of recently issued standards that are not yet effective will not have a material impact on our financial position or results of operations upon adoption.
