Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
At the first visit, the study doctor will check who can take part. Participants who can take part will be picked for 1 of 2 groups by chance.
Both groups will have 2 treatments but in a different order. The treatments are TAK-071 tablets or placebo. In this study, a placebo will look like the TAK-071 but will not have any medicine in it.
One group will take TAK-071 for 6 weeks, have at least a 3-week break, then take a placebo for 6 weeks. The other group will take a placebo for 6 weeks, have at least a 3-week break, then take TAK-071 for 6 weeks. The participants will not know the order of their 2 treatments, nor will their study doctors. This is to help make sure the results are more reliable.
The participants will visit the clinic at the beginning and end of each treatment for a check-up. 14 days after the 2nd treatment, clinic staff will telephone the participants for a final check-up.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The study will also evaluate the PK of TAK-071 in healthy participants (sentinel cohort) older than 55 years.
The study will enroll approximately 74 participants. An initial sentinel cohort of 10 healthy participants will be included to estimate age effects. Participants aged 56 to 75 years will be randomly assigned in 3:1 ratio to one of the two treatments:
* Sentinel Cohort: TAK-071 7.5 mg
* Sentinel Cohort: Placebo
Enrolment for participants aged 40 to ≤ 85 years in the main study will start simultaneously with sentinel cohort. Based on PK, safety, and physiologically based PK modelling data from sentinel cohort, dosing will be decided for the remaining participants. Participants with maximum age of 66 to 85 years, inclusive, will be enrolled at a dose of 5 mg, and the dose for subjects aged 40 to 65 years, inclusive, will be 7.5 mg. All participants will be asked to take one tablet at the same time each day throughout the study.
The remaining participants aged 40 years to \<=85 years will be randomly assigned in 1:1 ratio to one of two treatment sequences in crossover design:
* TAK-071 + Placebo
* Placebo + TAK-071
The study will be conducted in the United States. The minimum time to participate in this study is approximately 15 weeks. Participants will make multiple visits to the clinic and will have home assessments during the third Week of each 6-week treatment period, and will be contacted by telephone at 14 days after completion of the last period for a follow-up assessment.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Has a diagnosis of PD according to Movement Disorders Society (MDS) clinical diagnostic criteria for PD. Participants with DLB (i.e., dementia diagnosed before onset of motor symptoms or up to 1 year after onset of motor symptoms) are also eligible, consistent with MDS clinical diagnostic criteria for PD.
3. Has Hoehn and Yahr stage ≥2 and \<4 at the screening visit.
4. Has elevated risk for falls as indicated by at least 1 fall in the last 12 months before the screening visit based on the Fall History Assessment where in the opinion of the investigator the falls were a consequence of PD and are at continued elevated risk of falls per investigator judgment. Investigator judgment on fall risk may be informed by information such as, but not limited to, history, physical examination and/or a score ≥2 on item 3.10 on Movement Disorders Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III.
5. Has evidence of cognitive impairment as indicated by a Montreal Cognitive Assessment (MoCA) score between 11 and 26, inclusive and additionally can complete the cognitive assessments at screening (as specified in the study manual).
6. Can walk without aid for 2 minutes while doing serial 3 subtraction (with site staff ensuring participant safety in case of falls). Participants who require aids for walking can be included as long as they can complete the walk test without aid.
Inclusion For Healthy Participants:
1\. The participant is a healthy individual of either sex aged between 56 and 75 years, inclusive (for initial set of participant in the sentinel cohort) at the time of consent. Older participants may be enrolled after analysis of data from participants aged 56 to 75 years, inclusive.
Exclusion Criteria
2. Has dyskinesia of sufficient severity to interfere with digital gait assessments during visits (as defined by Movement Disorders Society - Unified Parkinson's Disease Rating Scale \[MDS-UPDRS\] section 4.1 "Time spent with dyskinesias" and/or section 4.2 "Functional Impact of Dyskinesias" scores greater than \[\>\] 2), or in the opinion of the investigator the participant's dyskinesia is likely to interfere with the digital gait assessments.
3. Has significant risk factors for seizures (a history of seizures as an adult, a history of brain injury, or other risk factors deemed relevant by the investigator).
4. Is considered by the investigator to be at imminent risk of suicide or injury to self, others, or property, or the participant has attempted suicide within the past year before screening. Participants who have positive answers on item number 4 or 5 on the Columbia-Suicide Severity Rating Scale (C-SSRS) (based on the past year) before randomization are excluded.
5. Is unwilling or unable to discontinue taking cholinesterase inhibitors and/or moderate or strong cytochrome P-450 3A4 inhibitors or inducers at least 30 days before randomization.
Exclusion For Healthy Participants:
1. Participants has body mass index (BMI) less than 18 or greater than 40.
2. Has significant risk factors for seizures (a history of seizures as an adult, a history of brain injury, or other risk factors deemed relevant by the investigator).
3. The participant is unwilling or unable to discontinue taking cholinesterase inhibitors and/or moderate or strong CYP 3A4 inhibitors or inducers at least 30 days before randomization.
4. The participant is taking warfarin.
